There is one exception. If the vehicle is in an accident and/or the air bag deploys, a 30 sec clip is of the incident is automatically uploaded.
There have been a few news stories where Tesla viewed videos from cars to identify missing people or those doing damage to cars. Maybe that data is kept in the car and Tesla can access it upon request? Either way, it is accessible to Tesla.
None of the companies say they will share data. If the police ask for it they will. They’ll just resist out act like they won’t.
Remember the terrorist couple in California with the locked phones that Apple wouldn’t open them? That was just a pr thing. FBI stated in the case that Apple immediately unlocked it.
I wonder if Tesla cars share real time driving problems such as; traffic, detours, etc to help others in the area.
