Right.
And there is the other side of the story : some people make helping them even harder. I am not specifying this driver, but it is an example. People trying to help but the doors are locked. This very much resembles many situations I have seen first hand. When you try to help someone and they are not helping themselves, or even worse making it harder for you to help.

I remember a work colleague a few years ago who was bullied by another arrogant colleague. One time the arrogant guy went too far, and I tried to interfere, but the weaker colleague put me in a bad spot in front of the boss; almost saying that he himself was wrong and the other guy was right !!! He was too scared to even defend himself in front of the boss.

Back to our story.
Maybe there was a reason for the driver to lock the door. I personally lock the car doors when using the ATM to get cash. But having the doors locked in this situation slowed the rescuers, and made it necessary to break the glass to be able to help.

Same thing regarding the outdoors. Many times I see TV shows where people fly in small planes, or hiking in the wilderness and colors of their clothes (or the plane colors) makes it hard to see them if they get into trouble.
