> And it would be great if it something that almost never broke as things that move a lot tend to. As far as I know static lidar are nowhere near as good. Keep in mind you're saying this about something that attaches to a car, which already has dozens or hundreds of parts that rotate at hundreds or thousands of RPM. > Then if the difference in quality is not actually that great, doing the development effort once will scale to millions of cars the next few years The adage "do things that don't scale" comes to mind. If your options are "have tens of thousands of autonomous vehicles" or "have none", I'm not sure how the second is better. And we know that hundreds of thousands or even millions of lidar units are being produced (cruise and waymo and co have multiple units per vehicle and collectively hundreds of thousands of vehicles).

Adding more rotating parts is exactly what you are trying to avoid. For example, go look at how Tesla designed the heating and cooling system. The integrated all the different streams of hot and cold in one system duplicate these parts that can break easily. In some cases it can simply not be avoided of course but you better make sure that you really need it if you are gone add it to millions of cars. > cruise and waymo and co have multiple units per vehicle and collectively hundreds of thousands of vehicles Waymo has vehicle count of a few 1000s as far as I know. I don't know about cruise but I don't think the have even 100k vehicles. Please show me a source. And even if that were the case, the build those fleets of quite a long time and the cost per vehicle they currently have is nowhere near close to what would be possible for a car like the Model 3 or future cheaper models. Margins in car industry are incredibly tight, car companies invest gigantic amount of capital to remove a few $ per car. These vehicles need to be able to be produced at a run rate of millions per year. If you are proposing to add something that cost 100-1000$ that is a absolute killer. In addition its an additional part that can hold up your production. This current chip shortage is a perfect example where having a Lidar would just introduce a whole host of new chips that might be in a shortage.

  You didn't really address the meat of the comment: The adage "do things that don't scale" comes to mind. If your options are "have tens of thousands of autonomous vehicles" or "have none", I'm not sure how the second is better. Waymo and cruise especially, but even a number of others, have demonstrated better autonomy than Tesla. Musk has been claiming full self driving is 6 months away for 5 years now, and he hasn't gotten that much closer.

    > Waymo and cruise especially, but even a number of others, have demonstrated better autonomy than Tesla. Have they? They have a different approach where they focus huge effort on individual Geo-fenced locations and they both are losing 100M of $ every year. Neither has given any timeline for general availability in all locations. The race, as far as I am concerned is still open. It is not at all clear to me that Waymo is ahead at what actually matters. > Musk has been claiming full self driving is 6 months away for 5 years now, and he hasn't gotten that much closer. The claim they made no progress is objectively false.

      > They have a different approach where they focus huge effort on individual Geo-fenced locations Where they actually have driverless vehicles. That's the key difference. Waymo and cruise have demonstrated driverless vehicles. People get driverless taxi rides today from waymo, and I think cruise as well. Tesla doesn't. It's still sitting in driver assist land and isn't particularly better than other luxury vehicle driver assist. > The claim they made no progress is objectively false. Thankfully that's not what I said.

        Then this would be a wonderful place to put your ego down and better explain what point you were making, because that's how "hasn't gotten that much closer" reads.
