Lies.
I just survived the 1,000 year storm in San Diego and my 23 ModelY's auto wipers still failed miserably. 4" in 6 hours and I still had times where they didn't trigger.
And just because it's cool (uhh, stupid), check out this Tesla in boat mode in downtown San Diego during the floods Monday....
