No, you are not supposed to put your car into park when you are stopped, that causes accidents. Say you are at a red light, you put the car in park, then you forget and the light turns green. You go to move but the car just revs and the person behind you slams into you thinking you were going to move. It make no sense what so ever that a car is not supposed to stay stopped when you foot is on the brake. That is the whole point of the brake.
