Cars do have that in what amounts to a TCU or Telematics Control Unit. The main problem here isn’t whether or not cars have that technology. It’s about the relevant government agency forcing companies like Tesla (and other automakers) to produce that data not just when there’s a crash, but as a matter of course.

I have a lot of questions about why Tesla’s are allowed on public roads when some of the models haven’t been crash tested. I have a lot of questions about why a company wouldn’t hand over data in the event of a crash without the requirement of a court order. I don’t necessarily agree that cars should be able to track us (if I buy it I own it and nobody should have that kind of data without my say so). But since we already have cars that do phone this data home, local, state, and federal government should have access to it. Especially when insurance companies are happy to use it to place blame in the event of a crash so they don’t have to pay out an insurance policy.
