If you want to talk about society, then this is about systematic security not individual security. If someone somewhere can push a button and flash your car with OTA firmware to drive you off a bridge, political assasinations become a lot easier.

In fact, with all this data they are collecting, you wouldn't even need to be the next edward snowden to get this treatment. You could set the firmware to target, say, every left-wing voter in america.

You don't even need the own the car with such behavior. Everyone becomes a pedestrian eventually.
