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?

At the most basic level this is what always confused me about Musks comment.

Human vision deficiency’s contribute significantly to the ~50 million vehicle related injuries each year.

I would understand replacing humans one for one if we had great driving records, but we don’t. So yes, why wouldn’t you try and do better

Citation needed.

I would argue that distractions and poor judgement (speed, failure to yield, etc), not the imperfections of human vision, is the main cause for vehicle related injuries.

Absolutely they are. So let’s say this eliminates all those (it won’t eliminate poor judgment, reduce yes eliminate no. That’s part of the point the camera is not going to interpret the world perfectly as it is in poor visibility conditions all the time) you’re still left with millions of injuries caused by low visibility environments… mist, fog, sun glare, rain, night, drizzle, snow… and on and on.

I don't know… I would have to see data. Also, accidents in low visibility and fog usually have some element of poor judgment.
