dynamic pricing can be trivially done with toll roads. Plenty of countries have toll roads with transponder tags. See, the big problem here is that you could share the transponder with a friends/family/co-workers and that makes spying more difficult. Doubleplusungood.

Therefore, we must install it right into your car, preferably at the factory, so you cannot remove it easily to make sure the spying data we get is of the highest quality.

They just want to spy on you, and with time control your car remotely, and they'll come up with all sorts of pretzel logic to justify it.

Spying. There are no other reasons.
