From NY Times: "Within Tesla, some argued for pairing cameras with radar and other sensors that worked better in heavy rain and snow, bright sunshine and other difficult conditions. For several years, Autopilot incorporated radar, and for a time Tesla worked on developing its own radar technology. But three people who worked on the project said Musk had repeatedly told members of the Autopilot team that humans could drive with only two eyes and that this meant cars should be able to drive with cameras alone."

Link. 

People sit behind windshields  with wipers, and still struggle in heavy snow traffic. Or with glare off an auto in front of theirs. At night, lane markers in headlight glare are a challenge.

Anybody with a car with a back-up camera knows about slush wiping as an almost daily duty.

And Elon doesn't? 

Get real.

Over huckstering might be a trait Musk shares with Trump. Tesla has pushed the envelope, given how the auto industry is. Tesla gave us electric propulsion via lithium batteries, while our U.S. of A. auto industry gave us the 1980 Cadillac where, big tech breakthrough, they took the 1970's tail fins off.

Without government pollution and mileage standards Detroit would still like us to have the same damned thing. Japanese firms ate Detroit's lunch, awakening the slumbering beast, and now, Elon says, "Two eyes good, cameras better, enough is enough?" 

 

Elon is slumbering. Or has Starlink starlight in his eyes. 

 

Finally, self-driving cars will be fine until they learn to do texting while driving.
