Don't forget the Black Box recording in modern cars that rat you out to police, insurance companies, and the car companies themselves on items that are none of their business such as how fast you drive, and how long before the collision it was that you braked. You certainly didn't knowingly agree to this in buying your last car, yet it's common for your opponents to be able to get this data after an accident, insurance claim, even a vehicle warranty issue. THIS SHOULD NOT BE ALLOWED WITHOUT YOUR EXPLICIT CONSENT.
You car doesn't call the cops and rat you out for speeding; the data only gets pulled after a serious collision with airbags deployed. At that point it's a legitimate criminal investigation and not simply a matter of privacy.
