&gt;The sensors really aren&#x27;t ready for it.<p>10+ year ago for Grand Challenge it cost some money (and good luck getting decent resolution stereo with decent FPS from a pair of 1M sensors, so most relied on lidar - $3K and you have minimally decent 3D of the scene ahead). Today the tens-megapixel sensors cost like nothing, along with CPU power to process it. One can have reasonable infrared too. Ultrasound sensors - cost nothing. Short distance lidar cost close to nothing too. Millimeter radar still probably cost a bit just because no mass production. When i see Google cars - Lexus SUV - they have at least minimally reasonable set of sensors. Nobody else comes even close. I don&#x27;t understand why.
