As part of an admirable but highly optimistic plan for a "Zero-Carbon Britain" by the year 2050, British Liberal Democrats announced plans to completely abolish gasoline- and diesel-powered cars by 2040. To aid them in their quest, the politicians proposed increasing Britain's car tax by £2000 (or roughly $4000) for the least efficient sport-utility vehicles.

Nobody has yet mentioned the specifics of such a plan, except to note that it would mandate automakers to cease production (in Britain, at least) and importation of gasoline- or diesel-powered cars, in favor of alternative power sources, such as hydrogen or plug-in electric. Moreover, the scheme will call for huge government investment in the national rail system — funded, appropriately enough, by highway tolls.
