Personally, I am fed up of the certain variety of motorist that is always complaining about fuel prices, speed cameras etc. Streets are for people with a bit for cars in the middle, not motorways with shops on the side. And even if a rise in fuel prices doesn't change the attitude of drivers, it could change those of people who don't drive - I for example have no intention of learning to drive and that decision is partly based on the high cost of fuel.
And as for concrete - concrete is a solid and is actually useful after its production whereas fuel, once consumed, does only bad for the environment. To put them together is silly.
