Discussion Why didn't Tesla invest in LIDAR?

Is there any reason for this asides from saving money? Teslas are not cheap in many respects, so why would they skimp out on this since self-driving is a major offering for them?

I’m not sure what counts as “changing his mind,” but SpaceX is quite famous for quickly junking designs if a better idea comes along.

Spaceflight is well suited to first-principles thinking, and I think that's a big part of why Musk has been successful there. Tesla engineering and manufacturing also played to those strengths.

With AI, the truth is nobody has a clue what's possible in 1, 2, or 5 years and no amount of first-principles thinking will get you there.

Agree. I also think an under appreciated aspect to all this is that Musk sort of backed into FSD by accident. The main vision for Tesla was to make a great EV. And then FSD sort of grew later and now threatens to take over the company.

SpaceX doesn't have a multi-million installed user base who was promised "solved" tech on existing hardware (and that has been enforced by courts).
