"In this fascinating public experiment, a German town wanted to see what
would happen to traffic flow if they got rid of street signs, lights and
other restrictions. The results are intuitive, but not what you would
expect! Everything got safer and faster. Would this model hold true
for other areas of infrastructure? Drivers must give way to the left
and not drive too fast. That's the only rule. Even the police love the
new system, and best of all, people are safer on the road. Drivers are
much more aware and use eye contact and instincts. People WANT to stop
for other people and help things move more efficiently. "
This seems ok for smaller towns, but I wouldn't want to try it in downtown Chicago. Still, it's nice to see that people will actually watch out for each other, at least when the necessity arises.
