_It's not a cultural thing, it's a human thing to be impatient._

True, but certain cultures see impatience as much worse flaw than other cultures leading to significant cultural differences in, say, crossing roads.

Seriously, if you ever visit Japan it will seem strange but people do almost always wait for the light.

I think this is partly is an illusion created by the wider roads. Longer jaywalking distance discourages jaywalking. For example in the nordics wide roads are uncommon so jaywalking becomes more common and safe.
