Gary Lauder's new traffic sign: Take Turns | Video on TED.com

Although Gary is a Venture Capitalist, in another life he'd had made an excellent traffic engineer. A traffic engineer doesn't just see a stop sign. He (or she) see's numbers - that, in this case, tell a story of inefficiency and waste. Gary does a great job of showing the thought process and math (easy math, at that) of how one stop sign can cost society over $2 million. If more people saw the traffic world like Gary, we'd have much less waste.
