I can speak with inside industry knowledge on this. Tesla is not a leader in vehicle automation. They are not even very competitive. They are very visible to consumer, but they can not compete without the use of optical radar. They have claimed to achieve close result with a camera, but this is not physically possible. Computer vision and camera sensor alone can not deal with road conditions reliably. They refuse to add any form of radar while others do. Their software is also not very advanced and is glorified cruise control.
