back to article Cruise self-driving taxi gets wheels stuck in wet cement

Just days after Cruise won the right to operate completely computer-controlled taxi rides in San Francisco at all hours, one of its units has got stuck in wet cement. Reports coming from both local media and social media on Tuesday show the front tires of a Cruise car sunk deeply into a drying part of fresh-patched road at a …

    Sooner rather than later, that platitude may be an unfortunate choice of words to use with these self-driving vehicles.

    As much as this will create mirth for certain readers, I am pretty sure that human drivers have done, do and will do this all the time... but it doesn't get reported (or if so, then just in the local papers' "Mirth" section).

      Re: Well...

      "Just as stupid as a human driver" is not the pitch for self-driving vehicles, though. They're supposed to be safer. If they're actually, as seems to be the case, much worse at actually navigating city traffic (and with the bonus of converting cell network congestion into traffic jams), what's the point? Just to remove more jobs from the market?

        Re: Well...

        The description of the concrete incident reminds of the principle of fail-safe, on perhaps the lack of it. Instead of assuming a road is a road until you see specific signs like a red "STOP" one, you assume that nothing is a road until proven otherwise. Is it flat but wet? Either not a road or a dangerously slippy road. Is it wet and raining? Then probably acceptable to ignore the previous condition but slow down anyway.

        The "10 car pile up" was actually "backed up" because this was fail-safe. There wasn't enough bandwidth and so the cars chose to not risk it. Although I am confused what they need all that bandwidth for. Are they streaming video to a dark room full of preteens trying to score 1000 points for hitting a pedestrian? (

          Re: Well...

          Yeah I would have presumed that the majority of the operations of the self-driving features would be done on-board, and therefore any bandwidth issues would merely stop real-time reporting back to the mothership, or the ability to cope with more advanced driving (and still leave it with the capability to drive around at least).

          Yeah, we meant a back up of traffic, not pile up. It's fixed now. Don't forget to email if you spot anything wrong.

        Re: Well...

        That's an awful lot of people driving through fenced off areas, barriers and/or lines of cones. Or are the rules different in the US (or at least some parts), where road repairs/construction is managed very differently such that it's possible to mistakenly drive into the fresh concrete/tarmac/asphalt?

        At least a few of those appear to be stolen cars, at least one by a drunk thief, so probably not the sharpest knives in the drawer were driving them, but still, after 30 years on the road in my current job averaging around 50-60,000 miles per year, I can't say i've ever come across roadworks so badly signed, marked out and coned/barriered off that someone would accidentally drive into wet concrete. Not saying it's never happed here mind, I just can't see how it might happen :-)

          Re: Having some empathy for the machines...

          Agreed, but the paucity of cones visible in the photos sort of indicates they didn't use all that many. In that situation, I'd expect there to be cones no more than a few feet apart down the length of the works. That photo implies the cones are something like two car lengths apart, at least. I'd also like to see the approach to the works too, just to confirm my suspicions :-)

        People have been "sabotaging" the self-driving taxis just by putting a traffic cone on the hood. The top of the cone blocks the camera view.

    stay well away ...

    "... a 10 car pile up following the Outside Lands music festival. Cruise explained that the festival created wireless bandwidth constraints that delayed connectivity for its vehicles."

    Err, the basic safety of the vehicle depends on having a good wifi signal (or even a good radio signal of some undefined kind)? That sounds like dangerous engineering to me! There's no chance they could guarantee it where I live in the UK, for example.

      Re: stay well away ...

      The WiFi is so the passenger can tell it where to go.

      The basic safety of the car depends on it stopping when it doesn't understand what is going on. But that's not the WiFi.

      1. Pascal Monett Silver badge

        That's not what I understand when I read "wireless bandwidth constraints that delayed connectivity".

        To me, that means that, if the vehicle cannot connect to the mothership in a timely fashion, it's ability to continue is heavily impacted.

        That, in my mind, eliminates any possibility of using that kind of vehicle outside of a well-covered city.

        No trips to the countryside are possible.

            Maybe someone could suggest plugging in an 8GB SD cars with a street map on it? That's the storage on my SatNav, which includes all of the UK and Western Europe roads in detail and much of the rest of the worlds main roads. I'm sure the system could cope with "knowing" where it is by matching the GPS co-ordinates with the street map and all those other "location awareness" sensors bristling around the bumpers, windscreen and on the roof for a short while.

        Is there a special reward for wasting hundreds of hours in a car every year for no money and achieving nothing ?
