Both Karpathy and must have explained it many times. The additional sensors add more signal than noise in the end. You also then have to decide which sensor system is correct any time they disagree. Also the entire road system is designed for vision. Lidar cannot read signs, see colors, etc. Humans can drive with two eyes. It's not insane to think computers can do it with 7 or 8 cameras.
As someone who has used Tesla FSD iterations for 4 years, their current system is quite incredible, and improving rapidly. It drives for me 95% of the time already.
And that last 5% is the toughest nut to crack. There is a reason waymo is way ahead even if they can not scale. Cameras are passive devices with relatively poor dynamic range and low light behavior. They are nowhere near a match/replacement for the human eye. Just try to picture a 5 year old at dusk or indoors and what you see will not be what you get.
