Basically everything he said as a justification (sourcing, firmware, etc.) applies to every sufficiently advanced part of the vehicle. By that logic, they should not be using touchscreens on the center console, etc.
Waymo has HD maps that require regular 'trawling', just like Google Street view. They are also very conservative in turns, generally avoiding unprotected lefts. They also are much less human-like.
Good point. I'm pretty sure it was poorer, Waymo really goes all-in on Lidar, they still top-mount it don't they? Waymo is also solving a much more constrained problem, with far fewer vehicles, so fewer accidents doesn't surprise me.
I guess you're saying that "cities are mapped, dude." But not mapped in anything like the way Waymo maps for this purpose: if I heard right, yesterday, mapped to the centimeter and very frequently updated to deal with any changes of any kind!
