I think my concern is that we are being lied to.

My opinion is irrelevent as I do not live in Virginia and am not a lawmaker, but I would want this to be tied to a vehicle telematic privacy bill that restricted how cars use telemetry data and gives consumers rights to control what is logged and who sees it and who it can be sold to.

Until we own the data our cars generate, I don't want active speed and acceleration constraint software for "chronic criminals" because inevitably it will be mandatory on all cars and remotely controllable by law enforcement.

I think the point is that we should aim to solve it without surveillance / sacrificing rights. So in this case, increasing the fines / jail time is at least one alternative.

How is this different to driving around with a mobile phone on?

Are you serious? I can choose to leave my mobile phone home if I want to. I can't do that with my car.
