I was not aware that so many people were involved with otherwise unnoticed accident, illness while driving and similar.You don't think that having invested so heavily in the Galaleo space systems to prove the EU is a force to be reckoned with that they are just going to let their egos float about in space and just give directions to a GPS system. They have to claw the money back, Blair the bar steward mooted this years back when he suggested paying by the mile/kilometer for motoring with a chip in your car.
A few, certainly, but enough for this enforced investment, and presumably enforced usage, to be of much use? Can't see it myself.
However as a tracking mechanisn with reporting via mobile communications it would be be equally deployable for road pricing, moving traffic violation reporting, most obviously in connection with speed, and a number of other potential concerns that a superstate might have.
Presumably it would be necessary to know the identity of the driver in order to make the first reponse team more effective in the event of illness. So will the system include some form of driver ID card, outwith which the vehicle is immobilised?
So in agreement to your suggestions, yes your ID card will be your ignition key along with your thumb print (we have to be sure the card is yours), the same to be used when you log on to the internet or make a purchase. Don't let Gordy fool you when he said he won't be following up on the ID cards, it wasn't his idea in the first place, it was a petty commie idea from the great trough in Brussels.
The fools did away with border controls within their petty empire allowing terrorist and crooks the same freedom of travel the honest enjoy, so in turn the honest must be burdened with the guilt of the crooks with draconian measures to attempt to control what will be essentially a constantly elevating system of repression, as the crooks and terrorists learn to counter their measures to catch them. But it's all for your own good, Gordy says so, so it must be true.
