Watch how a horse reacts while travelling

 I always thought that horses travelled better in a lorry, but this horse seemed not to have enough room to put his head in a comfortable position.  Unlike a trailer where they are at least able to put their head over the breast bar.  I was once told that  if a horse was travelled for one hour, it was the same as if he had walked for that hour.  Has anyone heard of this comparison?

My ponies travel facing backwards and I am not aware of them moving very much at all,  as  you can feel their movement in the towing vehicle.  I have a cheap intercom that I can plug in and listen or even talk to them.  I hear more rattling of  lead ropes and attachments and them sneezing than anything else.

It would be very interesting to repeat the exercise in a front facing, rear facing trailer and herringbone trailer or lorry.
