See you fell for the standard trap by assuming you are only giving up the speeders’ liberty.

A typical speed check camera will not register the license plates of vehicles that are not speeding.

What do you base this on? That’s literally a treasure trove of “public data” that those companies absolutely love to sell.

I agree with you in principle, but it's a fine line to walk. What about China's social credit score? It's all based on surveillance cameras that doc you points for breaking petty laws like jaywalking or littering. Yes, both are safety issues, but at what cost?

No it's really not a fine line. If you do something that harms someone else I think society should be able to curtail your liberty. Social credit is not really the same thing because when you speed you're increasing the likelihood of a devastating crash with another driver or a pedestrian. Having witnessed just such a thing a couple of weeks ago and having rendered aid, I can assure you there is very real harm. It is not something I will forget.

there's a reason why speed cameras are not very common in the US - they get vandalized by shotgun or arson if they're effective. doesn't matter if you like it or not, that's the reality of the situation.

they also ticket the owner of the car regardless of who is driving it, which is not very popular, to say the least.

I mean they can, but the burden of proof is on you to show that they do and that there is actual harm from it. I've yet to hear of a court case or warrant that was issued based on some notional speed camera database. If it's being issued on parallel construction that suggests there's some legal aspect of using those databases that prevents law enforcement from doing what you describe.
