Just curious about Elon's statement about engineering the sensors to be able to 'see' through metal. He was speaking of the side collision avoidance capability. My question is - has he eliminated all 'button' sensors?
I believe the ultrasonic sensors he was referring to are the ones the falcon wing doors use to calculate the opening arc (so as not to hit anything). I think the collision avoidance uses the sonar from the AP hardware, but I could be mistaken.
