Everyone is annoyed by speed bumps, but most of us understand the safety reasoning behind them. But what about us drivers who aren’t speeding? EdevaAB has invented a new smart speed bump that only becomes an obstacles for speeders.

These smart speed bumps are so intuitive, it’s difficult to figure out why no one invented it before. The bump, which is made up of two steel plates, uses a patented device to measure the force of a car’s impact. If the car is safely cruising at or below the speed limit, the plates collapse. But if a driver is speeding by, the plates stay raised.

At $1,500 per lane with a $50 annual maintenance fee, the bumps won’t break the bank.
