Having survived more than my share of driving catastrophies, I can safely laugh at many of these. Though it's pretty easy to see most of them coming LOL. I still feel sorry for the poor horses though. The people....not so much.
I can remember when I was about 4 or 5, my Dad and I were on a wagon having a runaway down a back road. I pointed to the right hand mare and asked my Dad "What would happen if that horse fell down?" He just looked at me and said "Oh, sweetie, we don't want that to happen."
That being said, our teams were always really well broke before we ever thought about taking them out among people.
