Tesla is very open about how this works. I don’t own a Tesla but I assume they mention this in some agreement when activating these features. By the way, they don’t collect all driving data. It’s too much data to transmit back home. They load test algorithms on to the car in “shadow mode” where they don’t control anything, then check for failures and send the car data from the failures back to Tesla. So very little data per car is actually shared.
