There's always bio-gasoline, just like bio-diesel or bio-jet fuel, it recycles the carbon as required and the proven tech already exists. It still takes 100 - 200 pounds of batteries to equal the energy density & storage capacity of 6 gallons of gasoline. Brazil has ran alcohol for years, even hoary old propane could do the trick. IF there was even a 10 pound battery that would store one gallon of gas energy equivalent we wouldn't be having this discussion. Personally I feel that the actual end goal is to force the public to purchase all new transportation equipment, equipment that is near impossible for the owner to repair. A guy with good lobbyists could make some real money doing that. It'd just be too easy to use landfills for carbon sources for liquid bio-fuel (synthetic fuel) production, but then everyone wouldn't need to buy a new car. It's that profit thing. And of course there's always public transportation. Electric trains, trams, busses & trolleys make the most sense of all in a city.
