I believe he claimed that since humans use their vision to drive that computer vision was more than enough.

I don’t know about you, but I also rely on sounds & feel when I drive. I also know that the human eye has evolved to detect motion, filter out extraneous information, and send just the important bits to the brain so that it doesn’t get overloaded with everything the eye sees. Computer vision is the exact opposite from that, having to process every bit of every image the camera sees.

Not to mention it has the potential to completely distract the driver when the light turns green and other traffic starts moving again.
