Ford says it will have a fully autonomous car by 2021

Ford and Chinese search engine company Baidu will each invest 75 million in Velodyne, a company that makes laser sensors that help guide self-driving cars. Velodyne, based in Morgan Hill, California, says it will use the 150 million investment to expand design and production and reduce the cost of its sensors. Laser sensors -- called Lidar, which stands for light, detection and ranging -- can also be used in conventional vehicles as part of driver assist systems such as automatic emergency braking.
