TED Global was last week. From 2010, here’s a 4-minute talk by Gary Lauder about the relationship between accidents, real estate, waiting for traffic lights to change, and how to resolve many of these problems with a new traffic sign.
It’s a nice bit of systems thinking. Given how fast Gary talks, I also recommend it as an afternoon adrenaline boost if you’re trying to stay off the caffeine.
