Well thats the problem isn't it. In the UK there seems to be a culture in
civil engineering to get away with as small as you possibly can. You see this
everywhere in roads, buildings and of course the hopeless railway loading gauge.

Not to mention the size of homes. I have seen bedrooms in which it
would be impossible to fit the smallest bed.
