Re: Road user charging
To use a car, you have to do this thing where you go into a public area and follow public roads where there is almost no restriction on the amount of cameras there can be or what can be recorded.
To use a car in Europe, you can either a) avoid all motorways or b) you have to pull into a toll every exit / motorway change and pay a toll (sometimes directly, sometimes by taking a card and paying at the other end, or sometimes by having to have a particular electronic tag).
To use road charging via satellite, you'd have to retrofit every single vehicle with an untamperable black box that ties into the location system, the telecoms system (GPS etc. DO NOT talk upwards!), and have some form of readable unique ID. That's quite expensive, even as a mandated item in new cars, and would take DECADES to deploy. It would also have to be Europe-wide, presumably. Nobody's going to sneak that into a parliamentary bill as a side-item. (And, no doubt, if they did the penalty for disabling it would be harsher than any charge they could put on you for using it). Nobody is going to launch an entire satellite system at the cost of billions on the basis of recouping their money on a system which will likely cause all kinds of dissent once it's mandated in cars, even if other countries accept it quite happily. That's NOT what Galileo is for.
To be useful for road user charging, Galileo would have to be more efficient than the road-toll system, more accurate, cheaper and actually do it. In fact, Galileo is merely something like an order of magnitude more accurate than GPS, which is already more than accurate enough for road charging. There's nothing stopping GPS being used for road charging TODAY. But we don't have a sniff in that direction because it's political suicide (watch the news over the years, listen out for hints like this, see how many are probed by the government to gauge public reaction and then never mentioned again - e.g. 80mph on motorways - NOBODY wanted it, which annoys me greatly as everyone then whines about speed camera deployment etc.).
My European friends are already shocked that ALL the tolls in the UK are not only optional, but also quite tricky to find if you don't know the UK and easy to avoid if you want to. Seriously. M6, Dartford, Severn, everything else is completely bypassable and even those are no great burden to avoid if you want. I was struggling to name toll roads beyond that when they asked.
Why is it that just because it's a car, it's somehow ingrained in your consciousness as more important than all the other freedoms you're having methodically stripped from you? Personally, I pay a couple of hundred pounds in "road tax" every year. That's a pittance. I pay more tax on my phone contract than on my car usage, and that includes the price of a phone! What's that equate to? Fixing one pothole a year? And then you have tax on fuel, which probably pays the wear my tyres cause to paint on the road and not one percent of the cost of the shit my car spews out.
My Italian friends pay a road tax, the same for petrol as we do (almost to the pence when you convert from Euro to pounds), and they pay at EVERY motorway change they ever make. You go one junction and you pay. You go change from major motorway A to motorway B and you pay again. And there is often no viable alternative whatsoever.
And do you hear them moan? No.
If you think Galileo is there to charge you for road usage, wait ten years. If there is road usage charges, likely it'll be a manual system (like tolls) like EVERY OTHER EUROPEAN COUNTRY HAS. Fancy technology in your car won't filter down to the populous for decades at least, even with mandatory laws. And certainly not if it relies on positioning networks that can be jammed and communications networks out in the middle of nowhere to talk back.
Honestly, paranoia is fine, but this is just rubbish.
What's Galileo's purpose? To tell the US to stuff their GPS systems up their bottom and provide more profit in scientific data and commercial usage (planes, boats, etc.) than any amount of road tax could generate in it's lifetime.
