None of those things are really private anyway. Private investigators, police, or stalkers can follow people from their house to wherever they go, and can identify you by your car's appearance even without the license plate. The difference here could be in the scale and ease of access to such data though.

Nobody seems to mind that Google Streetview shows cars. My sister visited her mother in another city at the time they drove past so now there's a permanent record that she was there at that time to anyone who knows what her car looks like. Is that a problem too?
