Unfortunately, a car like Tesla collects so much data. And it's only a matter of time before they start selling it. I don't know if any other car company that collects more data than Tesla.
You know they're not taking anything seriously when claiming with a straight face in the age of geoguesser that potentially hours of road footage, starting/ending with you literally driving into your garage, could ever be anonymous.
Gut check, sure, but I wouldn't trust the company that argued technically autopilot wasn't turned on in car crashes because they turned it off milliseconds before the sensed impact and blamed it on driver inattention as being a good, well-intentioned data steward.
Here’s one thing neither Tesla nor Hyundai have ever said: that they won’t sell the data. (EDIT: I stand corrected on Tesla, as per reply comment. “ We do not sell your personal information to anyone for any purpose, period.”)
They all do this until you press "I agree". Some do it even before.
