Boy racers don’t “automatically resolve themselves” through gaining experience. Without intervention you have to rely on reckless drivers gaining maturity, which is far from guaranteed, or having an accident that kills them or scares some sense into them, neither of which is desirable. The interventions currently are things like police catching them, which again is not desirable if an intervention earlier could prevent it escalating to the point where police have to get involved.

But my point is really that there are options to improve safety of younger drivers. If you want to reduce road deaths by 100, shouldn’t you target the group that is causing the most accidents, and the most severe ones too?

Morbidly you could just as well argue that the elderly are going to die soon anyway so the issue “automatically resolves itself” in the majority of cases too.
