> I guess all those sensors are actually more expensive than the cost of a human driver at this point?

Waymo inhoused their sensors and claimed a 90% cost reduction, but before that they were at $200k+.

Still, even at $200k+ that's not terribly high compared to a human driver once you amortize it over 8+ years. Higher than minimum wage, but really it's probably a matter of the upfront cost more than anything.

I'll also point out that even if they 100% solved self driving... somebody has to fill the things up with gas in most states, lol.
