Quite a few of the other drivers have also commented on the increase in buttons. Rubens in particular described the problems in a recent interview in motorsport. I don't see it as complaining, merely a statement of fact. Complaining would go along the lines of "I hate" or "I wish we didn't have this". You describe the button pressing in isolation but have you thought when these guys are going to be using both KERS and the rear wing? During overtaking perhaps?
