Thanks for asking:
1) A 10-year waiver on “crash safety” rules which encumber vehicles with a bunch of heavy stuff which does nothing to help get from point a, to point b.
2) Open market for individuals to produce ethanol (denatured, for fuel use) from whatever biomass they have available.
3) Remove all enviro restrictions which are preventing extremely high-mileage diesel autos available in Europe made by US manufacturers, from being sold here.
4) Government tax incentives to offer flex-fuel vehicles.
5) Some sort of nationwide flex-fuel backbone.
For a start.
I would add...use our own available energy sources as well. All of them.
