It is bad to have the gas pedal pressed to the floor?

Well think about this, what if that one time you press the pedal down all the way and another car happens to be coming from another road, or a child is crossing the street? Accidents happen everyday from people just messing around and people get seriously injured or they die. And especially in a neighborhood, go to a big empty road away from people and do that where you won't be risking others. Always better to be more on the safe side.
