Ever annoyed driving in some exclusive roads that have humps which can be stressing to break, change gear and push the accelerator again? Well here is an innovative idea that is good to have here in the Philippines.

They call it “smart” but I think it’s genius: Concern about the environmental impact of excessive breaking and accelerating has led Mexico to develop a “smart” speed bump writes USA Today.

When a driver is going the speed limit, the bump retracts into the ground. Says the company manufacturing the device: “With this speed bump, people will feel rewarded for obeying the law.”
