Not to mention possibly the most complex structure in the known universe, the human brain: 86 billion neurons, 100 trillion connections.
Beating human sensors wasn't hard for over a decade now. The problem is that sensors are worthless. Self-driving lives and dies by AI - all the sensors need to be is "good enough".
Well, in TFA the far more successful manufacturer of self driving cars is saying you're wrong. I think they're in much better position to know than you :)
2. since this is in context of Tesla: tesla cars do have microphones and FSD does use it for responding to sirens etc.
If it makes you happy, you can read "only vision" as "no lidar or radar." Cars already have microphones and IMUs.
