I love how this video praises LA for syncing its traffic lights to reduce congestion but LA is also known for being one of the worst cities for traffic and being congested. Only further proves the point that we should be building dense walkable cities that don't depend on the car to get you around.Great video. There is a parking lot in my home town that uses the motion controlled lights. The great thing about it is that it is a security light. If someone is in the lot late at night, it lights up, as well as saving money.
