It’s one of those areas where we want to regulate something we don’t really want to, so we’re stuck at a compromise that nobody says they are happy with but also nobody wants to change.

We set speed limits (so we did something about traffic deaths), but we don’t enforce them, because drivers would hate that. The upside of the existence of speed limits is that reckless drivers can be charged with speeding if they cause an accident. The downside is that police departments make a revenue stream of ticketing citizens driving at completely safe and reasonable speeds.

Some parts of Europe have automated average speed cameras. That’s way more draconian than a speed camera: they take a pic at each checkpoint, they know the distances between them, if your time is better than what you could do by driving at speed limit, you get a ticket. I would go nuts if I had to drive like that. It would work for autonomous vehicles, so I expect that systematic speed limit enforcement will coincide with the rollout of autonomous cars, which will be the time to stop driving on public roads anyway.

Another similar area is immigration, sorry for the off topic tangent, but I think it’s a similar dynamic. Anti immigration politicians say they want to make tough laws that keep immigrants out, but the laws are not enforced, because without immigrants entire sectors of the economy would stop working. Progressive politicians say they want lax laws so everyone is welcome to enter, but that would be a shitty law because you can’t run a country without borders. So the likelihood that we end up with regulations that allow the right amount of migrant workers and respect refugee rights, and then are actually enforced, is about zero.
