Having the data in the car's computer is the first step. Between a simple search warrant or insurance companies just deciding that they won't insure cars that don't give them driving data, it isn't that far away.

The articles I included only speak about interloc but when it was passed, there was talk of other more spy-like technologies that detects movement in the car that the computer could interpret as being impaired in some way (and literally shutting off the car) but once installed could be leveraged for other purposes by government & corporations.

As for not being covered, it was buried in last year's infrastructure bill & there was so much other stuff in there that the media focused on that it just didn't hit the main stream.

I have a huge rant just waiting but that is way too political & this is already pretty off-topic so I will stop.
