Where I lived in Europe (as an American), jaywalking wasn’t illegal. They didn’t even really consider it weird. After all, you’re just walking.

In fact, if you were in the street and a car hit you, the car driver had to prove that it was unavoidable to miss you, otherwise the driver was at fault.

It was also illegal to intentionally block traffic as a pedestrian unless you were at a crosswalk. But there was no law that made it illegal to cross the street anywhere.

Seems like the best of all worlds. And it’s easy to fully enforce the whole “blocking traffic is illegal” part.
