Don't forget that every self-driving car is a 360 camera that's able to capture real-time photo and video for the car's manufacturer (and whoever they want to sell this data to).
This would include images inside your garage, even when the car is off.
And they have microphones that can record conversations inside the vehicle, too.
These vehicles, in my opinion, are in many cases more privacy invading than phones.
And with Elon in government, with his BFF President at his side, concerns over deregulation and weaponizing these of moving spy devices seems like a future reality.
