Every project Elon does I hear him talk about cost efficiency. For the second richest man on the planet he's very concerned about money and cost. Even with his rockets, the conversation always revolves around cost per kilogram (or whatever) to get stuff to space, and how his main objective is to lower that cost as much as possible. Today he talked about the importance of keeping the Tesla bot inexpensive. The importance of making compute power cheaper per metric of computing. In regards to LIDAR - I think it's possible to drive safely without depth perception. One eyed humans do it just fine. It may not make sense to have LIDAR on every single machine you want to have vision processing with, including the Tesla bot. So it makes sense to solve problems without using it.
