Great point. Some time ago I heard a guy that designs roads in Europe explain his methods for making roads safer. The TLDR was that designing roads that require people to be alert reduces fatalities. So it is kinda the opposite of what you would think. Long straight roads are far more dangerous than roads with curves. Due to people not relaxing.
But politicians are not incentivized to really research their "solutions". They don't really have skin in the game. Worst thing that could happen is that they lose an election. Most of the time these things they propose don't even happen but they can say. I tried... but those dang republicans blocked me.
This. Along the same lines, as drivers get worse at paying attention and actual driving, more and more cars are being equipped with nanny devices like automatic braking and lane keep assist. This just encourages bad drivers to keep developing bad driving habits. It also introduces more potential for unintended behavior of the vehicle.
