Overtaking/passing on the right

Generally illegal, some people do it still.

4 way stops and whoever comes first can go

We get circles in high population areas, but not enough, I agree

No strict right of way when coming from the right

This is actually in our traffic laws, just most are dumb enough not to be able to figure it out :)

Right on red

Varies per state. (which is also stupid) It's like the circles, it's a density_safety/cost thing. If you don't have pedestrians, treating a turn with traffic as a stop sign can keep intersection costs down.

I'd also tac on abysmal public transportation, poorly maintained rail lines and horrible airport candor.
