> All these scenarios are possible with the addition of a $10-ish/hr driver today. Which easily multiplies cost by whole numbers if you allow multiple years for the hardware to break even. The fixed hourly cost for the driver is also why cabs are orbiting for hails (unless regulated not to) instead of waiting cold, further increasing cost per use. With passive minutes basically free, the economic threshold between passive waiting and active orbiting would be considerably shifted, resulting in additional efficiency gains.
