Even funnier the claim from the clueless Bryan Sinclair, Special Advisor to Don Brash
“we would be happy to receive any material (from you or from anybody else) suggesting that the forms of alternative energy that are developed (and there are obviously a number of these, already in development, including solar powered road vehicles and hydrogen powered road vehicles, but two examples) will somehow reduce the need for proper roading.” (Sinclair, April 2005, email conversation)
National seem to be arguing that either a demand or supply reduction in oil would NOT reduce the requirement for building more roads it follows that if we do not build more roads, spaghetti junction will become gridlocked with hydrogen and/or solar powered vehicles. (as in the above toon)
Anyone that seriously thinks this could be the case needs psychological help.
