The problem here is that Cruise launched prematurely, not that automated driving is intractable.
And this isn't just shade directly at Cruise, this seems to apply to all of the SDV companies out there. It's far from being ready for primetime. And speaking who was an early cheerleader of SDVs, and who continues to be highly supportive of their development, I'm increasingly skeptical that they are ready-enough to be tested en masse on public streets.
The recent Cruise meltdown re: Outside Lands was pretty concerning. In a natural disaster (like the types that the Bay Area is highly prone to!) the idea is just that you'd have all of these unoccupied vehicles sitting in the middle of the street preventing evacuation and emergency access?!
