Hope this isn’t too nitpicky but law enforcement is (a component of) regulation. But yes I don’t think progress is blocked on additional regulation. This breaks current laws. And I think more to your point new regulation doesn’t matter if we don’t enforce the ones we have today.

It is a broader, pre-existing problem. For example, most truck drivers in some states who don't tie down their rebar are not stopped, and it doesn't come up until another vehicle is actually hit.
