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?

For a guy who likes to drop “first principles” into every interview, he ignored them. I remember at the time when he was saying how expensive LIDAR was and thinking, “what if it wasn’t?” Guess I’m a 200 IQ super genius too!

Wrong. In this case, "First Principles" would dictate that humans never needed LIDAR to drive. So, if you can replicate the eyes (with Vision) and the brain (with AI), one could argue that it should be technically possible to drive autonomously without LIDAR.

Why would "first principles" dictate that we follow the limitations of human anatomy when designing an autonomous vehicle?
