Simply put, the Smart Speed Bump “can be configured so that if a car is going below 30km/h, the speed bump flattens; over 30km/h, the force causes the retractor to stay closed, keeping the speed bump active.” Click here for one more picture.

What a lovely goal: “Encouraging drivers to retain a constant slow speed will reduce the amount of stops and starts made, and thus, the amount of exhaust waste from the car. It is hoped that this retractable speed hump would therefore have positive effects on energy consumption and pollution.”
