It just has to be better than humans. That's why I think Tesla's approach is wrong. It tries to replicate a human driver. The argument against lidar is "we don't need a lidar to drive, our eyes and brain are enough". Yes, enough to kill thousands of people. You can easily find pictures of involuntarily camouflaged obstacles that take way too long for us to notice, and as expected, vision based system fail just like us, but lidar have no problem. It is hard for computers to be as good as humans when it comes to vision. That's something our brain is exceptionally good at, and a large part of it is dedicated to it. But here, for true self driving cars to be a reality, they need to be way better than we are. It means that we should throw every advantage machines can have at the problem, and extra sensors are part of it, don't be limited to visible light cameras. lidar, radar, sonar, IR, inter-car communication, satellite maps, use everything. And BTW, focusing on seeing roads is nice, but don't forget that there is more to driving that seeing roads. People communicate with their cars, sometimes in subtle ways, current self driving tech doesn't, and that's a big reason why they feel so alien and other drivers hate them. Self driving cars should communicate too, and better than humans.
