Are you sure. The EU mandates much MORE monitoring in most cases. Self driving cars may need to have camera's on occupants to monitor them during driving etc. A lot of the safety stuff in EU is MUCH more nanny state and CCTV is much more widespread it seems. Also very power data collection and centralized databases about everyone in the EU (ie, I don't think "states" or localities issue local ID's).
And no - CCTV is not widespread at all. There's far more CCTV in the UK than there is in the EU where I live now.
States do indeed issue local IDs. There is no common EU ID card and no common EU passport.
There isn't even a common immigration database for Schengen - although that's planned for 2023. (It was supposed to be 2022, but it's been delayed by a year.)
