Someone quite near to me says the same......"make petrol £20 a gallon. It'll keep the poor people off the roads and voila! no congestion......EVER!"
Quite controversial but a good discussion point!
You could draw parallells with something like fine wine, caviar or anything in limited quantities. When was the last 'Beluga Protest'? We don't need to drive as much and as far as we do. We choose to do so because it makes life easier.
I travel 120 miles a day to get to work. I don't need to, but I do it all the same. Ok, maybe slightly untrue as the place would fall apart without me

but I have a fuel card and fill up when needed. I do also drive the most economical car available in the range. Almost!
And do not even get me started on the price of Fish!!!!!
