A dynamic speed bump that will lower and give motorists a smooth ride if they are driving slowly enoughis in development in Mexico, USA Today reports.

Concerns over the environment — and the utter annoyance of having to brake and accelerate frequently — have prompted one Mexican state government to embrace a “smart” speed bump that could make driving smoother, without sacrificing safety.

The device, being developed by Mexico-based Decano Industries, automatically lowers into the ground when drivers go the speed limit or slower. Drive too fast, and the bump stays up.

The technology is relatively basic: The speed bump is formed by two steel plates that form a triangle sticking out of the pavement. When a car tire touches the plate, a patented device under the triangle measures the force of the impact.

If the tire’s impact is gentle enough — that is, if the vehicle is traveling slowly — both plates immediately collapse into the ground under the weight of the car.
