alt Hacker NewsSensor fusion is also hard to get right, since you still need cameras you have to fuse the two information streams. Thats mainly a software problem and companies like Waymo have done it, but Tesla was having trouble with it earlier, and if you don’t do it right, your self driving system can be less reliable.

I think this is the key. In theory - more information stream when fused together (properly) should reduce error. If their stumbling block is the "properly" part, than the rest of those justifications come off as a pretty weak way to sidestep their own inabilities to deliver this properly.
We have lots of evidence of similar strategies being used in other domains, this seems like an especially life-critical domain that ought to have high rigor and standards applied.

The response to the challenge shouldn't be whittling down your sensor-suite to a single type, but to get good at sensor fusion.
