Satnav-murdering Google slips its Maps into car dashboards Hyundai and Kia will be dropping Google Maps into dashboards of their US models, demonstrating the integration next week. The cars will hit the showrooms next year. Google Maps and Google Places will find space in the 2014 Sorento CUV from Kia while Hyundai will integrate the apps into its Blue Link platform used across the …
A ten mile journey will now take 50 miles to complete while the Sat Nav takes you round all the advertised businesses before you can get to your destination with all the associated risks of distraction while driving.
Street view will be like watching telly while driving, explain that one to the police as you go into the back of the car in front. Not to mention the data charges you may have.
Street view, soon to be banned while the vehicle is in motion.
Street view will be like watching telly while driving, explain that one to the police as you go into the back of the car in front. Not to mention the data charges you may have.
I don't know what your getting at here, the car needs streetview, it is how it sees to drive by itself. You didn't think the big G would let the fleshy ones actually have to do anything did you?
"Street view will be like watching telly while driving, explain that one to the police as you go into the back of the car in front. Not to mention the data charges you may have."
It'll be like Google Navigation currently on Android, it won't be a constant updating image, but will show snapshots of your upcoming turns/destination making them easier to recognise.
Instead of squinting for that street sign as you approach, you'll be able to recognise the co-op on the corner much earlier.
Privacy implications are easily addressed by noting that drivers with a smartphone are already being tracked unless they've jumped through the requisite hoops to switch off such tracking, and even then their network operator still knows their every move unless they pop the battery out, so there aren't really any additional concerns here.
Oh that's all right then. Move along there, no massive privacy fail to see.
Another Reg hack whose articles I shall no longer bother reading.
Indeed, I feel the same. Not to mention there is one crucial difference. With a phone, If I really want to not be tracked, I can pull out the battery, or just leave it at home. Neither of those options are possible with the car (I mean, I can leave it at home, but that defeats the point of having the car in the first place).
And if the EU in its infinate wisdom decides to legally mandate this in cars (not sure if it is actually law yet), I suspect tampering/removing it will be illegal to boot.
And am I the only one disliking the idea of being forced to have to pay for a cellular contract for the car?
The more I see the general direction of the automotive sector, the happier I am with a 30 year old car. They are actively making new cars less desirable to me, and unless they ban old cars one day, I don't plan on buying (I guess if they manage to indirectly force me to not have a car, they win on the eco front anyway, so a win-win for them).
Dear Sirs,
Isn't it rather so that if the government wants us to have cellphone capabilities in our cars, that it must provide that for us? If my (considering I'd be fully employed) employer wants to me to come with 24x7 mail reading capabilities I sure as tell him/her to give me a device capable thereof. If he then says: it should also work in the neck of the woods, I sure tell him/her to get me a device capable thereof.
On the other hand, didn't Brussel win a case against Microsoft for forcing people to use Internet Explorer (or rather for not having enough options available besides Internet Explorer)? If the Automotive Industry is hoping for long lasting service contracts by reselling mobile services, they sure as hell should provide any possibility. Even one where it says: I buy a car in Belgium-, yet live in the UK, just because I can (and because it is cheaper in Belgium)...
Or is Brussels hoping that the Automotive Industry is stupid, and therefore Brussels might cream off on yet more beeeeellion dollar legislation that costs treeeeeellions of dollars to start with....
Oh well,
Regards,
Guus Leeuw
"And am I the only one disliking the idea of being forced to have to pay for a cellular contract for the car?"
Under the last proposals I bothered to read, this wan't needed. The EU originally wanted a sim-free solution (or a "sleeping sim" approach), the mobile operators wanted a sim based one in order to force feed services that they could charge for, and I think that both options remain open. Car makers like BMW have reportedly teamed up with Toadafone to ream out their customers with a factory fitted contract sim providing a range of services as well as eCall compatibility, but BMW drivers like to pay more for less anyway. Up front costs for eCall were guessed at around €100 per vehicle, and basic eCall annual operating costs for the UK around £7.5m, say 30p per vehicle.
In the grand scheme of things the idea isn't a bad one (if it works in practice), and in its basic form isn't even much a threat to privacy. The threat is the inevitable feature creep into automated law enforcement, road pricing, and population monitoring. If you believe in "public services" you'll like all of those, otherwise you might regard the whole thing as a robotic beard-and-sandal in every car.
no, but there is a wonderful opportunity to have maps up to date and with nice traffic info: if a lot of drivers take a route that isn't on your map, it can be added semi-automatically. Same for speed limits, average speeds on a certain road, real-time traffic info,.... You give some, you get some....
"Privacy implications are easily addressed by noting that drivers with a smartphone are already being tracked unless they've jumped through the requisite hoops to switch off such tracking, and even then their network operator still knows their every move unless they pop the battery out, so there aren't really any additional concerns here."
I'm sorry to pull the national card here, but that is a view that you could only acquire in the US (where it is, AFAIK, also incorrect) but much effort has been spent on making people believe this).
The difference between mobile phone tracking and Google tracking is that mobile phone tracking can be done by a telco, can only release such data under warrant (although anti-terror backdoors have neutered a lot of due diligence requirements) - the fact that Google and Apple et al obtain GPS and tracking data is one that is expected to be reviewed in 2013 in Europe as it is typically done with implicit consent or even without awareness of the user.
Any EU nation has Data Protection rules in place that prevent a 3rd party from acquiring personal information without consent (and if it's "sensitive", i.e. you're visiting a doctor it must further be EXPLICIT consent as well) so it's just as well they only do this in the US models. If I ever get a rental so equipped I'll rip the fuse out.
Thus, back to the topic - may be OK for the US, no way in Europe - especially not now Google already has come under scrutiny (the request for information gave them a month to reply, and that time expires on the 16th this month).
An the fact that Google provides a opt out should protect them as well.
Only in the car situation. With respect to what is being investigated in Europe it's already too late for Google, and that's not just about failure to obtain proper permission of Google account owners, it's about gathering data of people FULLY WITHOUT their knowledge, permission or agreement. The crime has been committed (actually, they're still at it) so it's merely a matter of deciding on what the consequences are for Google.
What makes matters worse for Google is that they have already been prosecuted in other countries for the same issue, so it's not like they were unaware there was a problem ("Ich habe es nicht gewusst" hasn't been a viable defence since the Nuremberg trials anyway) so I do not expect any leniency. In this context, Schmidt's public statements could en up an object lesson in how press appearances can come back to haunt a company. That's why I'm waiting for Google's response to the French letter (unintentional pun :) which was underwritten by regulators of 27 different countries, because the response will pave the way for how all the complaints that have backed up whilst waiting for Google's reply will be dealt with.
"...it is typically done with implicit consent or even without awareness of the user."
Eh? I don't know about Apple, but Android makes it quite clear and gives you the option to turn it on or off as part of it's initial setup process - it has a screen that just asks you about location reporting. It is also very easy to find in the settings to change your mind after that.
If you also turn on location sharing for latitude services it also sends you an e-mail every few months reminding you that you have it turned on in case you want to stop using it.
However the traffic information you get from Google due to people allowing their location information to be shared is really good. Even some minor roads have traffic information on them which can give you a great idea of how much hold-up there will be. Combined with Google Now to alert you to start travelling to get to the airport or a meeting based on monitoring the current road conditions and your calendar works great.
The comparison was intended to remind people how much they're tracked already, but was perhaps too flippant.
UK Telcos do track, and store everything for two years with the RIPA removing any need for a warrant in the UK - I covered the subject in some depth back in 2007 and little has changed since then:
http://www.theregister.co.uk/2007/11/04/location_information/
For a really dramatic example there's:
http://www.theregister.co.uk/2011/03/30/cell_tracking/
The accumulation of tracking data is, or should be, a concern to all of us with insurance-by-mileage being the next likely battleground.
Bill.
Last week, I was rear ended by another car in a supermarket car park. The driver was setting her satnav for the journey home. A grand distance of 1 mile.
Do you really need to use your Satnav for this sort of journey? no you don't...
[icon] What I'd like to do to her and all those like her.
"Last week, I was rear ended by another car in a supermarket car park. The driver was setting her satnav for the journey home. A grand distance of 1 mile."
I understand your anger, of course, but don't blame the satnav which is merely a tool. As usual, many people should be told "This machine has no brain, use your own."
I'm actually sure, dear Sir, that the police couldn't be bothered with such a lowly offense for which they need 20 days to fill in the red tape...
They don't even come for a stolen bike... That's a criminal offense too... Sometimes they don't even come when one calls and says there's a burglar in the house... Remain and Quiet, si... Paf... Hello? Hello? Helloooo? Oh well... Click Tuuut Tuuut Tuuut....
Knowing Google, I'm pretty sure they will neglect offline functionality in favor of their cloudy solution. I, for one, do not want to consider a cloudy navigation for serious (and especially international) road trips because I a) don't want to be affected by network outages and b) don't want my mobile service bill to exceed my petrol bill.
Speaking of, will order an Alfa Romeo with TomTom integration via Blue&Me soon.
If the offline functionality works the same way as the current Android Google Maps app, then for every day use it shouldn't be an issue. I've not seen an 'out of data' error for at least 2 years, and that includes trips to deepest darkest Wales and Ireland. Even in rural England on GPRS I've been able to calculate a route and the phone will do its stuff, grabbing the full route info when it comes into decent coverage.
The other advantage of downloading map data is it should be fairly upto date; I've got Google to correct a map error and it was done within 6 weeks. AFAIK, the same error still exists on TomTom/Teleatlas, despite reporting it at the same time. At least it was on an upto date map circa 18months later.
Finally, regarding map errors, on my Dad's Ford Mfr sat-nav, the M6 ends somewhere in Cheshire, and restarts immediately. However, the two road elements don't seem to be joined, and causes the sat-nav to get itself all confused and upset.
"surely loading maps on the fly is going to be a downgrade, what if you lose signal..."
My point exactly. Imagine the nightmare and frustration of facing a loss of signal or a network outage of any sort in a stressful and critical moment while driving. Especially on a long and tiresome journey!
Value-added features and services that rely on IP connectivity are fine of course, but maps have to be stored locally on the satnav. Every other solution is plainly a joke, period.
You are aware that Google Maps caches the map data?
You can manually cache an area in advance in maps (I just did it for a trip to the Canaries over New Years).
Also Google Navigate pre-caches trips, so as long as you've got a data connection at the start of the trip and picked where you want to go to, it shouldn't matter if you have no data from that point onwards (unless you travel miles off the shown route, but it does cache a few miles each side just in case).
"You are aware that Google Maps caches the map data?
You can manually cache an area in advance in maps (I just did it for a trip to the Canaries over New Years)."
I just tried this feature and could barely select the whole Stockholm county before I got the error message "Selected area too large. Please zoom in." Sorry, this feature is just a joke and a pale shadow of full offline functionality which TomTom and their ilk have had for many years.
I wish I had taken my GPS when I went to Marin County last summer. I thought I could get by with the Blackberry since I had 4 different mapping/GPS programs. None of them worked in the vehicle unless it was on the dash. If I lost my cell connection the GPS quit working, and in Marin county I didn't have a cell connection most of the time.
I took my GPS out there a year earlier and it worked great.
I read this on Googles blog yesterday but it didn't occur to me the better solution maybe to just show your mobile screen, so thanks for the insight. I think you are correct.
The problem I have is that this will require another sim, another mobile contract to get data. Is it not time that the network operators changed their model and give you multiple sims you can use? I'm paying them a monthly contract to provide me with data, why do I need a separate contract for every device I own, phone, tablet and now car?
I refuse to go this route and just enable tethering on my mobile to use my tablet, but I wish they wouldn't make life that hard.
Twin sims ARE available, even for mere "consumers" (Well they are in norway) . . For work I have a phone and tablet with twinned sims, one for calls/sms/data the other is a pure data sim, but twinned to same contract and data allowance. So it doesn't matter if I decide to leave the tablet in the van and log a calls details on the phone. I can on my private phone contract get a twin sim for a tablet/3G or 4G dongle with a nominal cost for the sim itself, then fully shared data allowances.
Never come near the 8GB/month limit on my own tablet . .
Well, drivers could perhaps engage common sense?
If my phone satnav directs me somewhere I don't think it wise to go, then I ignore it. Rerouting usually sorts things out, but failing that I'm no worse off than I was in the days before satnav, having to buy a map, follow signs, ask directions, or in the absence of all the aforementioned trust my own judgement. Even if you've got a good hard copy map, in remote areas there's a modest degree of skill in using it well.
And failing all that, if somebody is daft enough to drive off a cliff then they should be encouraged to do so.
Sadly (and due to a lack cliffs) this rarely happens, what does more likely happen is that the satnav says "turn left in 100yrds" and the said 'driver' will turn left at the next opening in the hedge...... then wonder why the road is all bumpy and potholed and then what the 3 bright lights are coming towards him at 125mph.......
Just a shame that such stupidity is likely to take out other innocent people....
" The phone could log where you have been using GPS
Then later upload that data to correlate with any sheep rustling in deepest darkest Wales"
Lucky the concept of a smartphone that logs the user's location to a file that can be later downloaded is just science fiction.

Probably wont be long before car manufacturers are building Android tablets into the Dashboard and the rear of the front seats.
The driver could have sat nav running on the tablet in front of them, the front passanger could be browsing the internet, shopping or controlling what streaming video the kids in the back are watching on their tablets. The kids could be either watching streaming media (from a local source e.g. usb stick) or playing games.
Put a USB port somewhere so you could plug in your external HD or USB stick that contains your media for streaming. Build in Wireless connctivity so that the system can connect to your home network (or free open networks) to update apps and data.
There needn't be worries about 3g usage/costs as the google maps and data for your chosen country (or countries) could be pre loaded in the car and only updated when connected to a suitable wireless network.
Considering how cheap android tablets are these days then it should not add more than couple of hundred quid to the car price.
Build in tablets? Nope, slave touch displays. Almost half the cost of a tablet is full capability baseband processor, memory, batter & power management and the transmission capability. Looking at Nexus 7 tear down estimates, you could have a slave touchscreen for around $100, say one in front, two in the back, $300 total, around the £200 you suggest. Use the mobe as the network connection (and possibly the GPS chip), and you've no need for a new contract, you;ve got phone, contacts, music all to hand, and back seat passengers can stream media, or use the web for difficult questions like "are we there yet?"
Of course, the cost and the tech aren't the problem. The problem is the dinosaurs of the motor industry, still trying to charge £1000 for a built in satnav. If this is built in as standard it could work, but as an option the asking price would be about £4k because of the industry approach to options.
>Considering how cheap android tablets are these days then it should not add more than couple of hundred quid to >the car price.
That might be optomistic! Ford (UK) currently charge £250 for a sodding DAB radio to be fitted as an extra, for example. A tablet-based "entertainment package" is likely to much more. Still, there is little in what you have outlined that can't be achieved by the car-owner themselves, or by an independent car stereo installer if you really want a neat job of it.
Still, on the plus side, hopefully enough cars will come to have 3G/4G / Wi-Fi to make DAB redundant.
@ Dave 126: "there is little in what you have outlined that can't be achieved by the car-owner themselves"
Quite true. It's something I've been considering for a while. Not to use as a Sat-Nav as I have a perfectly good TomTom for that but for an incar entertainment system for the kids on long journeys.
Currently playing with an old Android phone with the aim of setting it up as an wireless AP and DLNA server.
>incar entertainment system for the kids on long journeys.
@Simon Round
Hmm, wonder if the tablet's accelerometers can be used to augment the video, so as to reduce the car sickness that can result if the brain receives different clues from the eyes and inner-ears! Kinda like the Optical Image Stabilisation used in cameras, but applied to output image instead of a sensor.
That was "more or less" there ten years ago, if you had the money.

"It has two flip-up 15-inch TFT monitors recessed into the seat backs".
It takes time before stuff like that reach production cars.
What I cannot believe is that a navigation system would completely stop working if the internet connection stopped working.
The cost of having an internet connection in my car would worry me less if I could afford a new car, no worry so to say. Time will tell how this will succeed (3d television!).
Also I wonder how not paying for your connection will affect your car.
Quote: "What I cannot believe is that a navigation system would completely stop working if the internet connection stopped working.".
It doesn't, the current version pre-caches the maps data as soon as you select a destination, with a few miles either side of the route just in case you go off course for some reason.
I would assume that they may be tweaking the apps in readiness for integrated car use anyway, for example an option to pre-cache all your local state/county/country data, which just updates periodically when it gets a data connection.
Android can't come to cars soon enough. The present generation of in-car computers suffers from the fact that every motor company seems to have decided to write its own software, a task for which they have neither the talent nor the resources. It's like the early years of mobile phones, or personal computers.
Perhaps I've been unlucky, but all the in-car computers I've used have dreadful UX: deep menus, hidden options, stupid defaults that you can't change. In my current car, the media player uses such a big clunky font that the titles are usually truncated. even though the names displayed on the satnav map show that it's quite capable of higher definition.
Nice plan, but wouldn't work in the UK where the "fair use policy" would kick in half an hour after bringing home a new car which decides to try to download google maps data for that small area known as "Europe" including ALL streetview images it thinks you "might" need one day. . . On the other hand unlocking this system could be fun with kids in the back editing the satnav destination from "Grannys house" to "Alton Towers" or similar. . . . .
Will they provide a phone dock/charging kit for those cases where the phone nav is mirrored onto the car (it's not just LR thinking about this either)?
Will they please change the awful synthesised voice guidance? Regardless of who provides the nav, if the system talks like a stilted robot it won't add to the quality feel of a Range Rover, let alone anything reasonably affordable. I'll take my old Becker any day over Google Maps/Navigation on my SG3 - it even says "Please" when giving directions, which must be novel for a German unit ;-)
They'll also need to think how they can build back in stuff that most sat navs include but Google doesn't. Custom displays would be nice, day/night mode, driving information as opposed to simple navigation. I use mine more for speed based on sat nav system, since swapping wheels for winter alters my actual car speedo gearing slightly.
If they're on about integration of drivers' handsets, why not go further and embed bluetooth OBD and the excellent Torque app? Or at least be able to mirror that info onto the car display as well...
Again IIRC from reading the latest issue of Top Gear, there's one manufacturer thinking of having the car security system tied to the driver's mobile phone - are these things going a bit too far?
"There is a question as to the value of dashboard satnav these days, when the aforementioned smartphone is so capable. Buy a new Land Rover and the dashboard-embedded screen will echo one's smartphone (as long as it's not an iPhone), making car-based satnav redundant."
Are you so retarded that you are incapable of grasping the fact that someone with an iPhone can install google maps, or a host of third party sat nav systems? You could buy tomtom, install google maps or a host of other options.
The fucking google app even has as it's listed features "Get Voice guided, turn by turn driving directions"
Christ.
Because they still work very well with no GPS signals. The GPS antenna on my car died but the satnav still worked perfectly. It uses the compass to know which way its pointing, reads the speedo and figures out very nicely where you are. I had no GPS signal for 6 weeks but the satnav was still spot on.
The other big plus point is you don't have have a stupid lump stuck to your windscreen obstructing your view and 50 miles of cable running off to a fag socket.
The down side is they add obscene costs to the price of a car.
You used a satnav for 6 weeks without any GPS signal whatever using just a digital compass and a speedo?
That is the most ridiculous thing I've heard - it's impossible. Even a 0.1mph difference or 1 degree compass bearing out would mean that the unit becomes disoriented after just a few miles. With no GPS is could never re-correct itself. The errors would end up cumulating to showing you as driving in Bangalore in 6 weeks.
What a cretin.
>What a cretin.
If the inertial (or whatever you call wheel speed differential etc) system is used in conjunction with built-in maps, cumulative errors can be drastically reduced.
And he didn't say 'just a speedo'; the car's CAN bus will happily tell any module information about each wheel.
His point that a GPS navigation system integrated with the cars drivetrain control can be superior to a plain GPS unit still stands... at the very simplest, the car will already know where it is when started up, allowing a quicker fix on satellites (as long as you haven't been towed, washed down the river etc)
Even without this smartness, Honda (or was it Toyota?) made a intertial navigation system in the eighties, using a microfiche-like system for map storage.
Are you seriously trying to defend this?
1) this is an inbuilt car sat-nav. It doesn't take readings from the CAN-bus (or any part of the OBD). It's a GPS it doesn't need to
2) What information does OBD say about 'any wheel', tyre pressure maybe, ABS and traction control? so what? What it doesn't tell you is the rotational speed of a wheel.
3) How will a car know where it is when it starts up - only if it knew where it was when it stopped, which it doesn't?
4) Satnav units built into a car don't have digital compasses, they use GPS to provide direction information.
5) Cumulative errors can't be reduced - unless you constantly tell the sat nav where you are (provide a point of reference manually). You don't enter a current location on any sat-nav - it knows where you are, it's a GPS!
6) A few companies tried to make a basic navigation system that worked a little like a tachograph. They didn't work. With GPS and SA turned on they used some speed and turning information but they didn't work very well either.
7) Do you really think that a SatNav manufacturer is going to spend 80% of their R&D budget trying to figure out a way of making the satnav work if the GPS receiver stops working by connecting in to compasses, wheel speeds, odometers, tyre pressure sensors?
8) You really think you can go for 6 weeks with a satnav using even the most amazing technology to read car sensors and still get any semblance of an accurate location?
Dave, with your silver badge come responsibility, use it wisely - this is a tech site not a youtube comments board.

"car manufacturers are just as keen to become providers of ongoing services (at ongoing cost) as everyone else."
I've noticed more cars with Integrated satnavs AND regular satnavs lately. The couple people I talked to said the map update cost more then a new satnav with life time maps, and the built in one was not very good to start with.
Current Audis already offer Google Maps/Places navigation with a cellular link. If you don't have cellular service then it defaults to the built-in maps. With the data connection, you get Google satellite and street view on the display. It works very nicely, and is much easier to control than using a smartphone would be (plus the display is bigger and turn information is presented in front of the driver.)
What I don't know yet is how the built-in maps get updated. The dealer didn't know last I asked.
I have a high-end Garmin Nuvi but would rather use the Audi/Google navigation.
Hmm - thanks for the tip. Given that Audi is German they will have to provide answers when I ask them to ensure my privacy, I do not want Google to track where I am, out of principle.
As for map updates of the built-in system, that happens via a USB socket somewhere (I think it's in the glove compartment).
Y'know, the thing about pre-portable shiny car controls was that they stayed in one place and were usually engineered to be where you expected them to be without the need to look for them while the car was in motion.
Now, car manufacturers vie with each other to put as much GUI crap in the center of the dash as possible, which offers the following exciting features:
Now you *have* to take your eyes off the road to do anything - like adjust your stereo.
Now the controls are never where you need them to be - right *there*, right now - without the need to activate the proper subscreen menu functionality applet and AAAARRRRGGGGHHHH!
Lest you believe I'm overstating the danger this fucktarded design presents, the count of people driving into my property at more than the posted speed limit while seeking just the right amount of bass or trying to get the graphic equalizer to go away so the GPS will show up or trying to find the graphic equalizer screen now stands at four.
The use of center dash displays should be banned by law since the bloody car designers haven't got the sense God gave cowpats. The use of multi-purpose, context-sensitive controls in cars should be banned because people demonstrably cannot drive and think hard about anything else at the same time and they need to watch the road more, not less, dammit.
People don't multitask. They timeslice. You can be killed or have large swaths of your front garden destroyed if the wrong task fills the wrong timeslice when the road conditions change abruptly in your vicinity.
My 2003 4Runner has a built-in nav unit. It always works, always the same way. I know it's not spying on me, and it never will. I don't risk a crash because a button moved in a flashy new UI update. It works in craggy mountains where internet service is lost. If I want services in the area, I have a Droid for that.
Most people buy cars for the long term, years. In contrast, Google et. al are constantly fiddling their services. Endless revamps of web pages and portals for most large businesses. What makes anyone think they won't do it to the car units? At best, you'll have to relearn the UI. At worst, they'll push out new invasions of our privacy. Google, Faceborg and others are constantly pushing self-serving 'features' that victimize their users
While updates can provide 'better service', they also provide a way to screw with a very captive audience. You can change your web browser easily, your phone for a couple hundred... buying a new car not so cheap.
Personally, the biggest issue I have with a built-in GPS is that it robs me of ANY choice to use the one I prefer. If someone thinks Google is better for them and they're not bothered about the privacy violations, fair enough. If someone else wants to use TomTom or Garmin that should be possible too, but you don't have that choice with any car manufacturer, an issue that until a few years ago was a real problem for Volvo users because that system was so useless it could have been designed by the architects of Unity or TIKFAM.
The main reason why you want an in-car GPS is because it also picks up from wheel sensors, which combines with a magnetic compass to continue guidance, even if you are out of range of satellites (for instance in tunnels), and if that data was part of some sort of Bluetooth exchange protocol it would give anyone a choice of what to use, and make smartphone GPS as good as its in-car equivalent (or possibly better as it can pick up live traffic data).
