Oh dear, resorting to meaningless statistics - always a sure sign the argument is being lost
Have you tried "urbanising" Ben Nevis, or the Peaks, or mid Wales. Not really possible is it? So when you take out the large swathes that are practically uninhabitable you are left with what we have, which is a fairly small area to chuck 70M people, 20M cars and 300k additional houses per annum.
If you dont believe me, leave your ivory tower and take a drive on most major roads and motorways at any time of the day and I'll think you'll see what I mean.
Anyway, this is degenerating, but thanks again for the useless stats; I recall the beeb regurgitating this garbage a couple of years ago just prior to the Govt ripping up planning policy guidelines!
