> incentivizes people to minimize dangerous behavior behind the wheel. Think very carefully about whether you want to be behind a person who is scrupulously obeying every single traffic law. Especially if you get 3 of them abreast.
That seems like... a good outcome? The privacy implications troubling enough to give me pause but the idea of more people actually driving at safe and legal speeds seems like a net positive, but perhaps there's some disaster scenario I'm not considering?
A car passing another at exactly 55mph while another car is going the same speed will take forever. We expect people to pull out, accelerate slightly, and then pull back in to get out of the way after passing even if that means you go above the speed limit for a bit.
Two lane roads often clog with truck traffic up hills. People pass these trucks on lanes in areas that allow it. The problem is that if you get too many people stacked up behind the truck who won't pass because they won't accelerate past a speed limit, nobody can pass and people will be trapped for hours at half the speed limit.
We call scrupulous adherence to rules "malicious compliance" for a reason.
