The problem with this line of reasoning is that the 'natural' speed limit of a freeway is a death sentence in the event of a crash.

I have zero sympathy for this. If you're doing 20 mph over the limit, you shouldn't be driving, whether it comes from taking away you car, or from putting you in a cage for a few weeks.

In that case, the road isn’t fit for purpose.

It's not the road that isn't fit for purpose, it's the human body plus the modern automobile that's not fit for safely handling a crash at 80 mph.

Either build better humans, better automobiles, or slow down.
