Why do most cars--I can't speak for brand new ones, but why do the rest have for the driver's side window control automatic down....but not automatic up? Is it harder to put your window down than to put it up? Does it take longer? Am I missing something? I am talking about power windows that, when you press the down button in all the way, you can go back to driving without a second thought while your window rolls itself down. Why, then, is it unnecessary to have the same thing when you would like to roll it up? Any insight would be great.
