last night i drove my gf and her ma around, and when we finished, my girl got out and shut the front passenger door at just the wrong time, when her ma opened the back door the door-bump got caught and curled up. luckly it didn't break, i just had to shuv it back into place, but im sure if care isn't taken when closing the front door when someone is opening the back door then this could damage something. just be careful with all your rides.
