I finished Adrian Newey's book last night, I have to say that I agree with him - make the regulation on power unit completely free, but give them 60kg of super unleaded for each car on Sunday morning.
They'd need tanks that were twice as big (or double the fuel stops.) Don't fancy being on the Methanol re-fuelling rig either, it's horrible stuff to handle.
