What happens when you remove traffic control devices (stoplights, signs, etc.) and the laws that come with them?
Several European towns have experimented with this idea. While many critics predicted a massive increase in accidents, fatalities, and general chaos, something beautiful happened instead.
Last year, I came across this story about a German town called Bohmte which removed all their traffic control devices - signs, stoplights, etc. The number of accidents and fatalities dropped to zero according to their authorities.
