Musk is complicated. I recognise he has done interesting things, my personal feelings to not detract from that. Even my very claim that he is used to Muntzing being a winning strategy is because (as I understand it) it did genuinely help to make the early Tesla models into products that were simultaneously affordable and not loss-making.
As for price, LIDAR has been built into high-end smartphones since at least the iPhone 12 Pro — 4.5 years ago. When LIDAR was new it made sense to avoid it, but I don't think that argument has been viable for a while now.
There's also the loss of ultrasonic sensors, which are cheap enough to be in budget teach-kids-electronics kits.
