Because I am not an investor. Tesla is definitely not the only good company, but investing is not what I do. But I always put my own money into companies I help create, otherwise it’d be wrong to ask others to do so.

Lidar is a method of measuring distance by shooting lasers and detecting how much time they take to return.
Computer Vision is a field of AI that trains computers to *understand* the visual world. This is basically reverse engineering human vision.
So....
Elon Musk
@elonmusk · Nov 20, 2020
It will be better than human vision by quite a margin

Has Tesla experimenting with using radar return intensity to assess surface smoothness (ideally over different wavelengths)? Could be really useful data for the NN, e.g. to detect changes in traction ahead (water, ice, sand, leaves, potholes, washboard, etc).
Elon Musk

Reality looks like a strange ghost-world at radar wavelengths. Almost everything except metal is translucent.

This is a misperception. SpaceX developed & continues to use lidar for Dragon docking with @Space_Station.
Just pointless imo for self-driving. If you’re going to do active photon generation, use an occlusion penetrating wavelength, like precision radar at ~4mm.

The next unofficial @SpaceX Raptor GIF - The LOX turbopump, which pushes about 3.5 times as much fluid as the fuel turbopump. How close am I @elonmusk?
Elon Musk
@elonmusk · Nov 20, 2020
I can’t comment on turbopump internal details, but you’re roughly in the ballpark. Wow, rocket turbopumps, especially if oxygen-rich, are insanely hard! Arguably, the hardest mechanical/fluids/combustion problem known to exist.

Why is Xpeng using lidar? Big deviation from copying Tesla. Xpeng says it will greatly improve accuracy - I believe it, but can severely limit scalability for their autonomous approach. Did they realize they couldn't make their Tesla-copy approach work?scmp.com/tech/innovatio…
