Ford says it will have a fully autonomous car by 2021
Ford's approach to the autonomous car breaks from many other companies, like Mercedes-Benz and Tesla Motors, which plan to gradually add self-driving capability to traditional cars.
[...] making personal cars more autonomous is dangerous, he said, because Ford hasn't figured out how to make sure drivers stay engaged and ready to take back the wheel when the car encounters an obstacle.
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.
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.
