First off let me tell you a few things about that video.
1. That driver should have known that the horse was upset and never entered the ring, or called a time out and called his handler in.
2. When the horse got lose they should have taken all the horses out. Why? Beacuse that horse knows safty in numbers. The other horses are in the middle and he wants to be with them.
3. Once the horses are out. Just let me run himself down on the outside of the arena.
Now let me tell you are few things about driving that I love. My horse was just a riding horse before I started to drive. Now he drives. Here are a few pictures of my horse and myself driving at a local driving show. I took champion for the year.
Here is the first time I ever drove a horse. This is tex and tory. A pair of driving horses my trainer (on the back) shows at CDE's. Sadly tory has passed away a few years ago. So now Tex (the lighter one) is a single.
Here is a picture of me and my horse at this years Darby and pace marathon. We have a lot of fun things with can do for driving such as ADTs and CDEs. Let alone the amount of driving clinics and shows.
Driving is more dangerous than riding bc the horse's vision is more limited bc of blinders and he cannot shy away bc of the cart/carriage.
That being said a bombproof cart horse and a bombproof riding horse are harder and harder to come by.
It doesn't deter me for wanted Buster Brown to get trained to drive next year.
If the video I'm thinking of, the one of the arab cart class, I seen it on one of the tv shows on Animal Planet. I think Untamed and Uncut? There was bees by the fence and that horse happened to get stung by one. I don't think that's really a fair video to say that driving is way more dangerous than riding.. The horse could have easily bolted under saddle by being stung too.
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!
Just to sway your fears, there's a 98 year old man who STILL comes out to the barn to drive his horse. That horse is as bombproof as it can get and even when it does do a small spook the man just has to say 'easy' and the horse comes right back and plods along. So long as you have a good trainer who can teach you and the horse, and good horse; driving is probably the best "retirement hobby" for people!
I just wanted to clarify that I think that driving has the POTENTIAL to be more dangerous than riding.
The video that I posted is one that I accidentally viewed soon after training my horse to drive. Boy, did it scare the crap out of me! I hadn't thought much about the risk of driving, at least not in that it differed much from riding but this video showed me that it does.
There's so much more to account for (a cart, possible passengers, limited vision by the horse due to wearing blinders, less contact ect.).
That being said, I think that the danger involved in driving correlates directly with the disposition and training of your horse. My horse is dead calm, super steady and as close to literally bombproof as they get. I feel just as safe driving him as I do riding him. I think that driving is a blast and I wouldn't want to deter anyone from trying it. Just make sure you have a very trustworthy horse and a knowledgeable trainer to guide you.
