So.....even if you add it to the price of US fuel, it's still cheaper than fuel in the UK? And British cities have just as much trouble with congestion as American cities do. I guess what I mean is that if this extra money is meant to be a deterrent to driving it's just not enough. I'm not sure what the price would need to be to be honest. I've been to Portugal recently and the price of petrol is just insane - in the order of $8-9/US gallon. And yet people sitll drive, larger cities still have loads of congestion. And Portugal is very poor by European standards.
