Sensor fusion is actually a hard problem. Yes, more different kind of sensors can lead to poorer results. Imagine having two different views in the world at unsynced points in time, and making decisions on that. It isn’t weird there might be a focus on LIDAR, or vision, but not both at the same time, at least for real time decision making.

I don't have to imagine this. My brain is doing sensor fusion every moment of every day. A lot of the time that involves conflicting data, and your brain has to decide on the most reasonable interpretation. When it's not at its best you get things like optical illusions, nausea, etc.

It's a hard problem to solve, but that doesn't mean it's a bad idea. I think most people would agree that human beings are better off with the overlapping set of sensors that are available to us compared to the alternative.

Google did it, so that argument is moot.

That is not how arguments work at all.

I work for Google and I like what Waymo has accomplished (disclaimer: what I work on is nowhere near Waymo). Tesla is making a different bet with different engineering resources. And why would Google give up their secret sauce to Tesla?
