The kicker for me is that the area covered by the ultrasonic sensors is essentially all blind spots for the cameras. The sensors currently are able to tell you when something too low to see is getting within a few inches of the car. It also gives an exact distance when parking, so I can know that I'm parking exactly 2ft from the wall every time. As much as they claim otherwise, it simply cannot be a matter of fixing it in software. The cameras can't tell you what they can't see. They simply don't have the coverage to do this, and clearly don't even have the coverage to hit parity with radar enabled autopilot either.
