Let's take Tesla as an example. Not representative, but still. They are constantly connected and log __everything__. They own the data, and they will happily use it against you if it serves them (ie, you die in an "autopilot"-related car crash, they pull your location data and show that you were leaving from a bar at 2:00 AM). Since it's not encrypted to a device key that only you own, like how iOS devices work, Tesla is also forced to hand over your data to federal authorities as soon as they get subpoenaed. It scares me a lot, frankly. I don't have enough money to buy a Tesla either way, but I don't think I could pull the trigger knowing what their data policy is like. Of course, with the way automated license plate readers are going, you'll probably be location tracked even with a "dumb" car, but at least the data would be more fragmented.
