I think you've lost the thread somewhat.
Let's go back to the post where I pointed out that your 4x4 is not a necessary working vehicle, but one that you need to support your chosen leisure pursuits.
Or is it ok for me to say that I need to travel 30,000 miles by plane each year because otherwise I wouldn't be able to get to my holiday villa, and so it's unfair that they're increasing airport taxes?
OK, lets get back to that (we can ignore the hummer as I was obviously not being serious. I am far to hard on my vehicles to use such a bling toy like a Hummer for towing a trailer). The 4x4 is an essential working vehicle in my business in the same way a plumber would use a transit to move his tools around. It enables me to move my animals to events and exhibitions where they are used as advertising tools to promote my products. I could manage without it for this purpose, but then I wouldn't have the use of the animals, and this would affect my ability to market the products dramatically (Like trying to flog a product without any working samples). Apart from this, I use the vehicle to transport the animals to the vets for various aspects of their care, and it offers substantial savings on the alternatives (vets charging £75 to visit the farm before they even examine the animals). To have a vehicle like this is a prudent business decision given the alternatives.
I don't really see what a holiday villa in the Algarve or wherever has to do with keeping horses in the way I do
The problem is you don't really understand how this sector of agriculture works, or how my product fits into it so you really are clutching at straws with your suppositions. Now bear in mind that the Equestrian sector is worth at conservative estimates £2.5 billion each year in the UK alone.
It could be argued that the economy gains far more from Equestrianism than from another pastime like cycling which even at best turns over 4.5 million cycle sales each year (most being through Argos & JJB for £99.95, with the quality end of cycles through specialist dealers making up a very small percentage of total sales), so why the big push on sustrans over bridleways ?

Oh, the BikeBiz article blows spindrifts love of Churchill insurance stats right out of the water (especially regarding the dangerous 4x4 drivers which he loves to drag up to prove how dangerous we are
