Shouldn't there be an 'Undo' Feature in Elevators?
Today while using the elevator to reach my floor by mistake by pressed the floor number which is next to me. Oops! Ouch! And I had to give all expressions for the mistake, as we normally do. But being a machine following our orders systematically, the Johnson's product religiously took my order, went step-by-step and stopped in the floor next and then again went to my floor.
I was feeling bad that the little elevator's effort and time was unnecessarily wasted in stopping at a floor which was not necessary. I do understand that for operator-powered elevators, the operator has full control on where the elevators should stop and also to ensure that the lift goes to a designated floors non-stop. However, similar to our software applications, can the elevator companies too make this 'Undo Floor Selection' a standard option. However, I admit that they should ensure that frequent press of this key should somehow be discouraged. I am just saying 'somehow' since I am not much exposed to elevator designs and hence presenting this as a common man's aspiration.
