The holy grail of vehicle road taxation, and state surveillance: GPS.

My GPS thinks I'm on the wrong street every time I miss an exit or start navigating under an overpass. There's no way GPS does this reliably.

I cynically assume they'll still use it as another reason to get that GPS into your car, which they've wanted to do for years now [1].

Yes GPS is behind times here. Galileo can do 1cm accuracy tho.
