Vision is almost certainly not the main issue with humans as drivers.
it's one of the reasons.
For sure, but my phone camera sees better than I do. Cars can make use of better camera sensors and have more than two of them. You can't just extrapolate the conclusion that human vision bad = vision sensors bad.
we can't conclude that LIDAR is better than a camera? Is it worth cutting the costs? LIDAR has everything that a camera has plus more.
Cameras are nowhere near the fidelity and responsiveness of human eyes.
