Enforcing such a policy via mass surveillance is a bit Orwellian though isn't it?
No wait fuck nobody likes any of that.
Okay what about buyback programs. What about trade ins. What about tax breaks and government subsidies for buying newer vehicles with less hem fuel emissions? What if instead of paying to enforce a law, you paid to change the conditions that lead to the problems that the law was created to address in the first place?
Already in place.

anti-theft cameras less so, because they are controlled by individual people, but as seen with Ring doorbells, the government can still access them, so it's pretty creepy.
