That assumes they're actually making a mistake, instead of habitually driving too damn fast because they think they're more in control than physics is.

I think it's more likely to lead to people slowing down and not doing stuff like weaving in and out of traffic so they can keep going fast.

Whenever I feel like traffic is moving too slowly for me, I think about how long it would take me to walk instead. And then I chill out and enjoy my private climate controlled capsule and maybe turn up my music.
