Ever been to New York or a similar city and watched people pouring out of a subway station at 8:30 am?

Now imagine every one of them is sitting in a sedan that is delivered out of an elevator, one by one.

According to Wikipedia, "Times Square–42nd Street/42nd Street–Port Authority Bus Terminal" station has 206,247 riders on each weekday on average. If we have 100 elevators which can transport a car every five seconds, it will take 172 minutes to move all of them.

With more realistic numbers (an elevator usually doesn't go down and come back in five seconds) it will be more than a day.
