Elevator Adventures

The Student Health Services at Penn has the coolest elevator that I’ve ever seen! It also took me a while to figure out how it actually worked! So you go up to the panel and you select the floor that you want to go to. Then the panel changes to a picture of the elevator bank and shows you what elevator to wait at. One the doors open and you step in, the elevator just takes you to the floor that you selected. I think it’s pretty cool and pretty efficient!  My only concern is what happens if you select the wrong floor ?!?
