> ALPRs. They're so bad for privacy.
Some countries have, or used to have, regulations saying that the devices aren't allowed to record the number plate details unless a crime is detected. I don't know how well that works since you're relying on the police to self-enforce that.
The UK doesn't have any such regulations and has fully embraced ANPR. They are being deployed everywhere now, for speed limit and red light enforcement, implementing toll roads and zones, enforcing modal filters, detecting cars reported in crime, detecting cars without insurance/tax/inspection, etc. and much of it is being converted to report to the "National ANPR Data Centre".
I wouldn't say I'm pleased about the privacy implications, but most people here are fine with it and seem to derive more benefit from it than harm. Vehicle crime is one of the UK's biggest problems, and I know several people who've had their stolen cars recovered thanks to the system, and ~everyone supports cracking down on uninsured drivers. It's become more controversial lately due to low emissions zones and the potential future introduction of road pricing, but that isn't really a push back for privacy reasons.
I just think in the UK, people don't have a cultural expectation of privacy when driving.
