I've seen older footages of Tokyo (1960s) where the streets were pretty chaotic and dirty. Also Miyazaki described how the rivers used to be very polluted, which inspired the bath scene in Spirited Away. Not sure at what point it changed.
Also remember Americans telling me Seoul being dirty in the 80s, but is generally cleaner than western cities these days.
The West Coast at least used to be more rule-abiding. Many years ago now, I remember a co-worker complaining he had gotten a ticket for jaywalking in San Francisco I think. Of course, these days you probably need to murder someone to get the police involved in SF but I digress.
And when I worked in a smaller city fairly near Boston, when going out to lunch, I was pretty much the only person who was inclined to just cross the street while my coworkers waited for the light.
So it does vary.
That would give people way more time to clear out the right turn lane each cycle and reduce incidences of people trying to force their way through pedestrians.
But people don't even respect the basic "don't walk" so it's asking a lot...
DC is one of the worst; it sometimes feels like the pedestrians and cars are in competition with each other, and each just violate the rules because there's zero expectation that the other will follow the rules.
