You want less of something, tax it. Trains, buses, bicycles, etc. are not or should not be goals in themselves. Using fossil fuel for manufacturing and not vehicle fuel is not the goal in itself. Less CO2 (or other pollution/resource use) is the goal, so tax all fossil fuel and let markets figure out what is efficient. And if you think expensive gas is harsh on the poor, address that separately a la basic income proposals. This all is quite impractical, so people will just go on searching for the keys they dropped in the sewer under the lamppost where they can see.
