This is analogous to a single car, single driver, where the car helps get the person from "point A" to "point B" and the single driver represents the driver and sole passenger of the vehicle. If this were a single driver on a energy-efficient motorcycle or scooter, than would be reasonable, but people often drive alone much bigger vehicles,what Jeff would call "over-provisioning".
