Without trying to sound self-righteous, the issue is a little wider than just saying "I demand to use my car because it's convenient and I'm going to get upset if I have to pay more for doing so", which seems to be where many people stand on this issue.

That may be some people's point, but not mine. There is no suitable public transport to where I work. If I moved, it would simply mean my wife had to travel the same distance instead. The proposed costs would be in excess of £2000 per month, even if petrol was entirely free and there was no road licence. (I don't pay £2000 a month in tax either, Richard!) So there are only two economically viable solutions I can see. Either my wife or I leave work, which doesn't do us or the economy any good, {though of course in time we might find a new position), or, more likely, we buy a second property, because we could buy a quite reasonable property paying maybe £1000 per month. And that's great for the housing shortage, isn't it?
