I don't think you understand how the complete system works.
You're relying too heavily on external cameras as being critical to the functionality. They play a supporting role and are limited in effectiveness in dark or low light conditions yet Autopilot works at night.
When I mentioned redundancy, I wasn't referring to overlap of data or vision, it was overlap of necessary sensors, the hardware.
How do you know that the 4 cameras behind the windshield along with radar aren't enough for it to function well enough to park itself in a safe place?
Sonar also is unaffected by road film, slush and such. They literally see through metal.
Since Tesla is equipping all its vehicles with the same sensor suite for self-driving, the company doesn’t have the luxury...

Using a non-LiDAR approach, Cornell researchers have discovered they can detect objects with nearly LiDAR’s accuracy and at a fraction of the cost.

"While not as anti-LiDAR as Musk, it appears researchers at Cornell University agree with his LiDAR-less approach. Using two inexpensive cameras on either side of a vehicle’s windshield, Cornell researchers have discovered they can detect objects with nearly LiDAR’s accuracy and at a fraction of the cost."
Maybe just radar and the 4 front cameras along with the extensive data in the NN are enough?
Radar isn't affected by road film, rain, slush, it's sound waves. How do you know that your friends radar shut down?
Here's a few links that may help you better understand how it currently works.
Several updates to Tesla's Autopilot system were revealed Sunday in a company blog post that at times sounded somewhat otherworldly, as it referred to UFOs landing in zero visibility.

Radar is forward looking and can see up to 160m, and can see through almost anything.
That and the 4 front facing cameras behind the windshield are the primary sensors. The camera behind the windshield handles wide angle, narrow angle, front, sides, 60m, 80m, 150m, 250m.
GPS also plays a small part.
To think that Tesla has completely missed the obvious is what's ludicrous. That's just a confirmation bias. You've shown that card repeatedly.
Every time Autopilot disengages, Tesla knows. Do you think they've just ignored those incidents without determining why?
Are you aware that what we currently have is not FSD? There aren't any non-employee Tesla's that have a functioning FSD. Why don't you just wait to see how Tesla has addressed your concern before you write them off as incompetent. The disengagements that currently happen could be computer/software related. You just don't know and neither do I but I'd be willing to bet that Tesla does.
