I really don't care for your analogy, speeding is a choice that puts others at risk and I think safety rules that protect everyone from each other, are far from infantilism. But also, we shouldn't let perfect get in the way of good. Blocking 100mph+ may only improve safety on faster roads, but that's still a gross improvement. A few people a year are caught doing 150mph on 60mph single carriageways near me. Far more nationally, far more never caught, and exponentially more on superbikes. If there's no legal reason to do 100mph on any road, why not just stop it being an option? Remove that temptation. It will save far more lives than it costs.
