Who is that person who gets on the elevator and proceeds to push a button that is already illuminated,and is this the same person who when driving feels that just the act of signaling gives them the right to change lanes whether there is room OR NOT!

When I get on an elevator and the button is already lit, I will push it again or push the door close button to make the doors close faster. I dont use my turn signals, so I dont know what the hell you are talking about LOL !

I will sometimes press the lighted button a couple of times to see if it gets things going faster.  As far as changing lanes, I like to hit the gas (especially on my bike) and move right on over.
