The puzzle piece you are missing is that sensor fusion is not an easy problem either. The Tesla perspective is that adding N different sensors into the mix means you now have N*M problems instead of M.

I hope that's not their perspective, because that perspective would be wrong. There are entire subdisciplines of control theory devoted to sensor fusion, and it's not particularly new. Rule 1: More information is better. Rule 2: If the information is unreliable (and what information isn't?), see rule 1.
Some potential improvements are relatively trivial, even without getting into the hardcore linear algebra. If the camera doesn't see an obstacle but both radar and lidar do, that's an opportunity to fail relatively safely (potential false braking) rather than failing in a way that causes horrific crashes.
Bottom line: if you can't do sensor fusion, you literally have no business working on leading-edge AI/ML applications.
