BS
I'm going to have to call BS on that unless you can name me a few of the current model cars you've managed to get into without causing damage.
None of the usual tricks that your friendly AA man used to use to get you in when you'd locked yourself out of the car work on new cars. For example popping the top of the window frame and reaching in with a coat hanger? Double fail. Popping the frame won't work on most new cars and even if it does there's nothing for you to get hold of with your coat hanger.
However it isn't much of an issue anyway because it's much harder to lock your keys in the car than it used to be. Remember the days when you could do something like locking the door from the inside and then hold the handle up when you close the door? That sort of thing doesn't work with modern locking systems. We just tried it with a few newisg cars outside and we couldn't lock any of them without using the key or fob.
One we thought we would manage it on was a Nissan with an auto lock feature. Unlock the doors and don't do anything and it locks itself after a couple of minutes. So we thought if we unlocked the car, dropped the keys on the drivers seat and shut the door it would lock itself. Nope. As soon as you open one of the doors the auto lock feature is disabled. It only auto locks if you unlock the doors with the remote and then don't open any of them.
