Self-driving car

"But conventional automatic cruise control fails at speeds of less than 30kph (20mph). To circumvent this problem, the new car uses lidar—short for “light detection and ranging”—a measuring technology similar to radar but which uses laser beams rather than radio waves to measure distance and determine the speed of other vehicles. As light waves have shorter wavelengths than radio waves, the technology works at shorter distances and lower speeds. Indeed, the prototype has a distance-keeping system that will brake to a standstill, and move off again when the car in front moves."
