I hate all this "We have to protect you" crap they put on cars anymore. My FiL's car does the auto lock as soon as you put it in gear. Irritates me a bit. Then my wife's whole family has to lock the doors almost the second they are in the car, like someone is going to run over and grab you.
And if they discover the doors are not locked while driving 60, they are in a panic. If you are going 60 and some guy can run along side and open your doors, you have bigger things to worry about than if the doors are locked. I bet peeling a locked door open isn't much problem to some guy who can run
60 or 70 mph.
