> In reality there are signaled crosswalks

On signaled crosswalks, it obviously only applies when the light is green for pedestrians. Somebody's near the crosswalk and they have green light = you stop. It doesn't matter if they want to cross. Simple as that.

> Multiply by a nation of hundreds of millions and you get a lot of near misses and accidents.

Nation size doesn't matter for this. Poland based this law on experience from Lithuania which is 20 times smaller than us. It worked for Lithuania and it worked for us. Why would it suddenly be worse for 350 million people if it worked for 2 million and 40 million?

> ignore anyone who talks like that from any side of the issue because they're probably gonna make it worse and not better and piss everyone off in the process and make the problem harder to solve

When they teach you to optimize polynomials at school, they tell you to look for zeroes of the derivative and check which one is the global maximum. But they also tell you to look at the edges of the domain, because the highest peak might be outside the domain altogether.

I'd argue that the US is so car-centric that any effective solution will be outside of the perceived "practical" domain.
