Jay walking, it is illegal in some places, almost never enforced

Illegal in some states I think. Fun fact when the term jaywalking was introduced, the term jay was a legitimate insult, meaning something like country bumpkin

Not sure, but I think so. But it definitely not legal in Germany!

I think if you are at a designated cross walk you can cross anytime traffic allows even if the signal isnt walk.

Funny thing is that in poland the fine for jaywalking is lower than a fine for crossing on a red light, so you can just go around the crossing
