It's just not a serious technology. Street-by-street speed limit data exists, and where it doesn't, there are laws across the US as to what speed limits are based on area. Tons of map data to tell you where is residential and commercial, a street and a highway, an on-ramp, and so on.

But FSD doesn't abide by speed limits, and Waymo does, and it is truly self-driving.

So, it's all bullshit. Since day one, it's never been a real attempt at autonomous, legal, safe driving.
