Tesla has cars with Lidar on the road to check the models as well.
And who says anything about entitled, they have spent a huge amount of effort and therefore money into a solution that they think will be better.
Nobody with Lidar has delivered either so what is better is still an open question. Tesla has picked their strategy and working on it. Others do the same.
My point is simply, not that Tesla has the perfect solution, rather the idea that Tesla is operating based on 'ego' is idiotic. Elon Musk and his companies have repeatably shown that they are very willing, comically so, to throw away work and go back to the beginning if they have encountered a problem. E
lon is well known for not falling into the sunk cost fallacy. Consider the manufacturing of Model 3. Consider Starship being planned to be built from carbon fiber, and switching to stainless steel.
Do you really believe they know lidar would be better and they not changing because of what Musk said 4 years ago? That is literally the opposite of how his company have operated.
