When (not if -- just a matter of time) Tesla pulls off FSD with only vision and without LIDAR or RADAR, the other companies will look pretty ridiculous with their hardware protrusions all over their vehicles gathering data yet still can't deliver Level 5 autonomy. They'll eventually get there, but first have to learn for themselves that they've gone down some dead-ends.
I applaud Tesla for realizing RADAR is isn't needed and then changing direction. All the while, the others are still stuck on thinking LIDAR is required. So far, only Tesla appears to have the volume of data needed (among other things) to accomplish the machine learning by capturing the billions of real-world miles from the fleet of Teslas.
Sure, I'm tired of waiting, but this is a super difficult thing to solve. Once Tesla does it, I think we'll see them applying their same approach, technologies, systems, and tools to other problems and making rapid progress with those.
