I'm not sure I agree with this mechanism for getting there- sort of what I meant by agreeing with most of it. If it was phased in over the next decade it might be more reasonable- but I would need to know more details before saying anything definite. And then this probably wouldn't be the kind mechanism that would drive the issue. A better route, might be to make methanol more available [cheaper] and then "force" car makers offer this option to car buyers at a "reasonable" price.
But perhaps the better angle is via World Bank type investment in methanol production in Africa [and/or elsewhere]. This would of course need done in a smart way- but we got pretty smart guy in charge of World Bank at the moment so maybe he can fiqure how to do this.
