If you want your doors locked when driving ... how hard is it really to lock them yourself? If you were in a high crime area wouldn't you think about that anyway? I don't want someone trying to rip my door handle off. I had that almost happen because the child safety lock was engaged on one side and not the other, so they got out easy at one place we stopped, sat on the other side and I head a loud noise (I am a little overboard on babying my car, but it is new!!!). I just feel it is pointess since it would take you a second to either hit the button on the door or the one on your key fob thingy. Auto-down on the windows is more useful for me hehe
