Elevator Cancel Button

I live on the third floor of an 11 story building. The elevators right by me have floor indicators, telling me where the elevators are sitting. Often, the elevators will be in motion, and as a result, I take the stairs over the incredulous stares of the passengers in the elevator, who were forced to stop at the third floor.

There are also times when the elevators do not appear to be in motion (say one is stopped at the lobby, and one at the 8th floor). In this case, I surreptitiously press the down button and lazily float down those two flights.

Sometimes, however, just as I am pressing the button, one of the elevators begins to move. Now I am in a situation where I have already pressed the button and committed the unwitting passengers in the elevator to stopping at my floor. Depending on how high up the elevator is, I either wait it out and deal with the sarcastic comments ("Oh, was the third floor too hard to walk down from?"), or make a mad dash down the stairs to the first floor.

None of this would happen if I could simply press a "cancel" button and continue on my way. In addition, a very useful analogue for the *inside* of the elevator would be a similar button, to be used when you accidently press the 8th floor button instead of the 10th, or the 2nd floor instead of the lobby.
