Ford has announced that they are developing autonomous cars. They have already done tests with the Fusion Hybrid research vehicle using four LiDAR (Light Detection and Ranging) sensors that scan the road 2.5 million times per second.
The sensors send ultraviolet light within 61 meters and from the information gathered by the system, they create a three dimensional map of the environment. Through this map the vehicle is driven so as not to hit on something.
Ford has not said when it is going to release an autonomous car on the market, but they merely said that it appeals to all shoppers.
