I was assuming humans and self-driving cars both get revenue from riders, but don't get paid in between. And I'm interpreting utilization as the percentage of the time that riders are paying.

The human's time has a cost, and even if the rider doesn't explicitly pay it, it is factored in to the labor cost of the driver.

The machine's time cost is time-based depreciation, which is pretty low.
