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.
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. So we are literally talking many, many years of millions of lidars produced and integrated (and not replacing other sensors) to maybe have a slightly better outcome.
However that depends on your sensor fusion and how the lidar handles weather conditions and other complexities.
But I am sure its all ego.
