Why would you need Youtube videos? In 3-4 years, every major city in China will have large fleets of fully driverless robotaxis on full display. L4 or even L5 autonomous capabilities are achievable TODAY if you are willing to use lidar. So why doesn't Tesla use lidar? The answer is COST. The cost of placing a complicated (and bulky) lidar system on a car could be somewhere around $10,000+ if the U.S. tried to do it today. Tesla is highly focused on costs and making sure the cars are affordable. Adding the price of a lidar on top of an already expensive car is a terrible idea if your target market is the private individual.
Plus take a look at the Waymo lidar system. Look how BULKY it is. How many private car owners want to own a car that looks like this?
Looks are less of a problem with a robotaxi. And a robotaxi will pay for itself after a certain number of rides.
Also China has one more
secret weapon. China is the only country in the world that can produce the
low cost, SMALL SIZE lidar system. Take a look at the Huawei car. It has lidar, but can you see it?
