I'd imagine sensor fusion in this context isn't a singular problem right? It seems entirely plausible that for Tesla's system, it's straightforward to integrate cameras where the resolution is known and data is homogenous in a certain way, and that it's hard to integrate and use radar data into that system.

The Model 3 has a ARS-4B radar and these things usually already do perception for you, so the output is a list of vehicle velocity and pose. Given what I know about Autopilot , I don't see how is that hard to fuse. And I doubt the supplier of the radar (Continental) gave Tesla raw data access.

I just think there's more to the story than we're getting. Impossible to tell for an outsider though.
