Government agencies used to be able to do their jobs, but ever since the Reagan era, that has diminished. And as a result, since 2010 pedestrian deaths (and deaths for vehicle occupants) has actually increased, after falling for decades. If you want to do dangerous stuff, like riding a motorcycle, free climbing, etc, you should be able to. But when you're doing stuff where the risk is entirely placed on someone else, that's literally the point of regulation.
