>What makes lidar for use in self-driving that expensive? I have a robot-vacuum with a lidar that wasn't all that expensive. Waymo says it cost $75,000 for the lidar in one car a decade ago, and in 2019 they said they got the cost down to $7,500. So at the time Tesla decided to forgo lidar the costs were certainly very high. I'm guessing the range in your vacuum is multiple orders of magnitude less than a car. Waymo must have been betting costs would drastically fall over time. No idea if it's a lot less than 7500 now.
