> system: signal lights tell me whether or not I can pass through an intersection, so that I do not have to attend to potentially high speed traffic from a variety of directions.
You know I noticed this... I lived in a country where people obey traffic laws, and in a country where they very much don't.
I witnessed many more traffic accidents in the country where people are used to relying on the traffic lights to tell them if it's safe or not.
Whereas in the other country, everyone correctly assumes that the other drivers are completely insane, and so they stay vigilant.
