Why would a car that expensive not have a LiDAR sensor?
The supplier he was using couldn't supply lidar fast enough, and it was at risk of slowing his manufacturing.
So he worked in a way to not need it, and tell everyone this solution was superior.
Read about this somewhere. Iirc, Elon felt cameras were better than LiDAR at a time when that was kinda true, but the technology improved considerably in the interim and he pridefully refuses to admit he needs to adapt. [Edit: I had hastily read the referenced article and am incorrect here; link to accurate statements is linked in a reply below.]
He didn't think they were better. He thought Tesla could get away without the more expensive lidar. Basically "humans can drive with just vision, that should be enough for an autonomous vehicle also." Basically he did it because lidar is more expensive.

that was never true
Found the article! I had breezed through the thing. I was incorrect about the LiDAR/camera thing. Instead it was: ‘Elon even admitted that “very high-resolution radars would be better than pure vision”, but he claimed that “such a radar does not exist”’
He, of course was incorrect and proven incorrect, but ‘the problem is that Musk has taken such a strong stance against [LiDARs] for so long that now that they have improved immensely and reduced in prices, he still can’t admit that he was wrong and use them.’

I don't even understand that logic. Use both. Even if one is significantly better than the other, they each have different weaknesses and can mitigate for each other.

Fuck em.
props to the LiDAR car for trying to drive through that heavy rain - does it just have enough resolution to see through the droplets to determine that there isn't a solid object within braking distance?
EDIT: actually maybe it didn't, and just stopped when it realised that it couldn't see through the water?

Sounds like they are mad at them selves and not realize it. Think it though people.
