This is what I have never understood. People seem happy to sit behind horse riders for some considerable distance before pulling out, giving them a massive berth and tottering past at a 2nd gear idle in case the horse gets startled before giving a cheery wave and gently accelerating.
If only the same courtesy could be extended to cyclists....
A horse, weighs a considerable amount of pet food, with a human rider perched on top, hit a horse or the horse jumps onto your vehicle its going to do a considerable amount of damage to your vehicle,and to you and your passengers, possibly involving a huge blood loss from the animal,(seen a few vehicle horse interfaces),along with was the horse insured for your damage /injuries, was it trained to be on the road and lots more questions that may invalidate an insurance claim.
Oh and its a nice touchy feely animal.
Where as cyclists are squdidgy, dont have insurance, or a licence,dont pay road tax to use the roads, even though it doesnt exist, are seen as a pest to some drivers, and are basicly expendable to some.
