Dynamic restrictions would also be a problem, either by forcing location tracking into every vehicle or relying on (eventually) outdated database or flakey computer vision (cameras can get dirty). Then you need to consider what action to take when a vehicle is exceeding the speed limit. Are you going to disable the throttle or apply brakes? How soon and how hard? Keep in mind that older vehicles don't have this system, so braking may cause an accident. Disabling the throttle might also cause an accident either by upsetting the car with unexpected weight transfer or indirectly because the car could not get away from danger.
My experience is they all have satellite connections and require some level of telemetry. My car throws a persistent check engine light and error message on the radio if you disconnect the telematics control unit.
The only problem my car has now is an occasional failure of Android Auto with a time sync error. There's an ota update for the head unit available that may or may not be related. I don't plan to install it. I only put 1000 miles on the car before removing the cellular connection so they could log the engine break in period as being done correctly for warranty purposes, so I'm not sure if it was an existing issue or related to removing cellular.
Afaik, having built in gps is not an issue since it's a receiver and doesn't transmit. The tracking issue is because of cellular.
I would check if the low trims exclude telematics before buying a car. If so, you can probably remove it from the higher trims but do your research.
