Ford Motor Co (F.N) said Tuesday it plans to triple to 30 the size of its fleet of self-driving test cars as part of an effort to accelerate autonomous vehicle development. In an announcement coinciding with the Consumer Electronics Show in Las Vegas, Ford said it will begin using a new, lower cost LiDAR sensor made by California-based Velodyne. Ford said it will be the first automaker to use Velodyne’s new solid state “hybrid Ultra PUCK Auto” sensor.
