1. Cheaper sensors
Electronic eyes provide a full picture of the road, but the combined cost of high-res cameras, radar, lidar, and other sensors totals (conservatively) $75,000. Optics engineers are working on less-spendy versions. Waymo, for one, has claimed it's made a rooftop spinning lidar for just $7,500. Autonomous vehicle companies keep in-house development hush-hush, but, as engineers keep tinkering, the costs will drop further.
