It's scary ! You ride 2 abreast, on the roads and one of the horses is quite nervous and while the horse is "learning" you're putting all the other road users at risk.
Nobody is being put at risk at all. The horses are under complete control at all times.Its important to look ahead, to be aware of all around you, and to be able to act accordingly to prevent any risk. As you should have been doing, then you would have seen the white van with plenty of time to react and to get out of its way. Or were you so dangerously close to the rear of the horses hoping to incite them to spook so that you could prove a point to yourself? If you were keeping a sensible distance from the horses then you would have seen the van in time to move over."simples, love" If you and yer mate want to go on horses, why take them on public roads? why can't you ride them around a paddock or field, then your friends horse can be as nervous as he likes and the only people at risk are the 2 individuals who chose to ride the horses in the first place.
Then the horse will never get used to anything outside his field. Just because you sit in your 4x4 on the drive because you love it so much doesnt mean its being driven y'know. The horses are schooled in a menage but need the experience of roads and real life. Sorry, "real life" may be a bit of an enigma to you...google its meaning if your not sure. Please forgive me if you were using your horses to get to an important engagement, shopping or an emergency etc which if you only have a horse as a form of transport then that is quite understandable. If you were just posing in your jodhpurs then God help us.
By the way, I have ridden horses, several times.
Then as I said, you cannot ride. Takes more than several times round a field to learn. Thank god you dont go out on roads. I'm aware it's an animal and as such it's unpredictable, just like dogs. 1 x 15 year old kid on back of 1 x unpredictable animal = high risk. Simples love.
