Better place automated robotic 2-minute swapping stations cost $500K, but a 6-
pump gas station costs $1M. So we are in the same ballpark.
Most of that time is driving in and out. So a dual swap station can refuel
cars as fast as a $1M gas station if a gas car takes 6 minutes for roughly the
same infrastructure cost.
