On a slightly more serious note: I really wonder what’s going on in your mind when you press that button and cross anyway. Is it just because “I don’t care”, or is there more to it? If so: what?
EDIT: In case it’s because you don’t care: why do you press the button then?
I think most people have been guilty of this at least once in their life. Sometimes you’re just walking deep in thought, approach the lights and press the button and realised you never really looked at the traffic conditions.
Something similar has happened to me as well, BUT the question arose in my head when I saw this guy walk toward the button confidently, press it without stopping and crossing immediately. Then it got me thinking.
