In my humble opnion the amount of "humor" one draws from situations such as this is directly proportional to the distance one is from said event. I sincerely doubt that if it was one of your loved ones driving across said bridge daily you'd find ANY humor in the situation whatsover.
Kinda reminds of a situation I had years ago with my oldest son. He had to have surgery to repair a lazy eye and I was worried to death for him. He was only two. When one of my friends heard about it he tried to calm my fears by letting me know this was "only" minor surgery and I had nothing to worry about.
I told him my definition of "minor surgery" was surgery on one of HIS children, not mine. Then he understood.
