Because tech (any tech) is even more fallible than humans.
Comment on Elon Musk May Have Made a Huge Mistake on Full Self-Driving That It's Too Late to Correct.
Doom@ttrpg.network 1 month agoSelf driving cars should be flawless and personally, as someone who does not have any professional experience in tech, I do not understand why you’d ever rely on human senses to act as sensors for a machine. We can’t even see all the colors, why would you not give this thing like four different versions of detecting things? If I have a self driving car I want a fuckin radar on my windshield that knows where every object within 40 feet is.

Except the radar doesn’t know where every object is. It can’t detect stopped things while traveling at high speeds.

the large majority of current self driving cars have radar, lidar, ultra sonic, and cameras. their detection sets overlap, and complement each other so they can see a wide array of things that others can’t. focusing on 1 and saying “it doesn’t see X” is a very poor argument when others see those things just fine

The point is that to be truly autonomous when vision is the only fail safe reliable sensor, then vision MUST work to have a truly autonomous vehicle.
You can’t rely on radar without vision or lidar because it can’t see stopped vehicles at high speed.
You can’t rely on lidar in rain/fog/snow/dust because the light bounces off of the particles and gives bad data, plus it can’t tell youanything about what the object is or might intend to do, only that it’s there.
Only vision can do all of those, it’s just a matter of number of cameras, camera quality, and AI processing capabilities.
If vision can do all those things perfectly, maybe you don’t need those other sensors after all?

i don’t think anyone is relying solely on radar - that’s the point. every sensor we have as fallible in some way (and so, btw, are our eyes - they can’t see through things but radar can in some cases!)
even if you CAN rely solely on vision, why hamstring yourself? with a whole sensor package, the algorithms know when certain sensors are useless - that’s what the training is for… knock 1 out, the others see that it’s in X condition and works around it
if you only have a single sensor (like cameras) then if something happens you have 0 sensors… our eyes are MUCH better at vision than cameras - just the dynamic range alone, let alone the “resolution”… and that’s not even getting into, as others have said, the fact that our brains have had millions of years of evolution to process images.
the technology for vision only just isn’t there yet. that’s just straight up fact. can it be? perhaps, but “perhaps in the future” is not “we should do this now”. that’s called a beta test, and you’re playing with human lives not just UI bugs - and there’s no good reason… just add extra sensors
