Well that is an absolutely horrifying video, and I am glad you posted it because I was considering taking up driving as a "retirement hobby"! I've changed my mind now!
your going to let one video change your mind? Here are some photo's for you to consider before you decide:
Wouldn't this be fun to trot down a back dirt road? The steady foot fall of your favorite mount, the crispness of fall, watching your horses ears as they go along?
Before you say that driving is "bad", if you look close, there is a 3 year old little boy in my lap helping me drive two 1800lb Percheron mares hitched to a wagon. Not all driving animals are high strung or hot or going to cause a wreck:
First time I drove a team, my mare Smoke and my mentor who is on the box, Bob Brennan, with his mare Rosie, in an arena, having only about 16hrs of driving time with a team and a wagon with no undercut, I placed 2nd:
In an arena, it was windy, the loud speakers were right above us on either side and a large crowd, I am on the lines. Doing public education with our mares, you can tell they are so upset
The point I am trying to make, don't let one video of a horse we don't know the history of, how far along in it's training, how long it has been driving, etc. put you off on a sport that yes, holds its dangers, but so does everything else we do with our equines. A well trained driving horse, or team, can bring so much joy to you, your family, grandchildren and children a like. I don't compete anymore, nor do we do public education, we just enjoy. You develop a bond with your driving horse, they trust you and you trust them and when that happens, there isn't anything you can't do. I have been in situations with my mare's that yes, I should of thought it out a bit more, but....I trusted them to get me through the rough trail and the tight spot, I had the knowledge to get us out as well and we did it. Have I had a bad wreck and/or witnessed them? Absolutely.
Go driving with someone you know and who is skilled.
