And common sense might tell you that waiting at a lone traffic light in the outskirts of a town in the early morning, sun rising, no car in sight for some hundred meters in each direction, does not add value to society?
I come from a city where people jaywalk(Stockholm). Jaywalking makes the city extremely walkable, and quite frankly I suspect it was designed with jaywalking in mind. It is obvious when someone is not from Stockholm - they wait for the signal.
I don't get the ease of jaywalking in many other large cities I've been - Zürich comes close. In the UK, even crossing at a green light feels dangerous.
