Looking from the other direction, say an elevator can handle 60 cars an hour, so given staggered commutes it might serve the needs of 100 drivers. If having elevator access let you cover most of your commute at 100mph, what would that be worth? Multiply by 100 drivers, and 10 more to get from annual revenue to capital expense and I'd say million dollar elevators are no impediment at all.
