Actually, light travels slightly faster in space than in air. It travels at the cosmic speed limit. They can be used to detect obstacles in a distance of around 30 meters and measure their speed. They are placed in bumpers or on the sides of a vehicle and warn about possible collisions with objects or persons. In addition, they can be used to support the parking process.
