I find myself reminded of an article about a German town that stripped out their lights and signs and just had everyone drive by basic priority rules. Apparently this sharply reduced incidents.
Some time ago I drove through that town without knowing anything about it. I didn't realize that they had such a concept, it just felt really stressful, because your normal expectations and intuitions don't apply.
This basic principle also explains why roundabouts (traffic circles) are so much safer than traffic lights. They feel unsafe to drivers, so they slow down and pay attention, instead of blindly trusting the lights.
