And robot vacuum cleaners :) Although there's some hostility to cybershow here I'll reference a couple of episodes because surveillance is a frequent talking point. In this [0] one the discussion is exactly what you're talking about.. cars, and the incident with Tesla employees sharing 'funny' road traffic accidents.
In this other discussion about CCTV in general [1] two notable things came up:
1) From a security POV, there's an impotency of digital surveillance. It is a tool that works well as post-facto analysis (such as arresting a bunch of rioters the next day). But it has less value in real time unless you also have human resources - and in most cases (except in dangerous war zone) if you already have them they're superior to any electronics.
2) Communities are sold surveillance by an "insecurity industry". It's a big business. But they rarely reflect on its value or other effects. Surveillance is a sign of poverty if you take all quality of life factors into account. Overt security signals inner insecurity and social decay. The more cameras you can see in a place the 'poorer' that neighbourhood since a truly wealthy society is one with high trust.
