"In fact, Al Gore proposed a 12 cents a gallon BTU tax on all fossil fuels in 1993 and when Congress killed that he cast the tie-breaking Senate vote for a 4.3 cent a gallon gas tax increase." And check the source -- yes, a conservative columnist. And I've seen gas fluctuate on its own, by more than 12 cents in the past year -- twice.
http://www.conservative.org/columnists/divine/001005dd.aspRe: mandatory retirement, aside from the automakers' "planned obsolesence" (where the car is so junky that it falls apart or costs too much to fix after a decade or so), I haven't heard Gore endorsing anything of the sort for older vehicles. There is a provision regarding the phasing-out of CFCs in vehicle air conditioning systems, but that was agreed to by Reagan/Bush when the US decided to support the Montreal Protocol for protecting the ozone layer. And these systems can be replaced with ones using different chemicals, so there is no need to get rid of the whole car.
While it's true that (with the exception of new gas-guzzlers like the Hummer) we'd be better off in terms of fuel use and air quality if we could replace less-efficient vehicles with ones which use less gas and emit less pollution, and cars today tend to be more advanced than they were 15 years ago -- the vast majority of environmentalists don't think we should FORCE people to change vehicles -- something they would do anyway, in time. If anything, banning older vehicles would make things worse, because there would be heaps of rusting cars lying around, and even more pollution and resource consumption from the need to make replacements!
Environmental policy experts would rather leave it to market forces (gas-guzzlers cost more money to run), or inspections like the "Air Care" programs being tried out in various municipalities. (I suppose that some people will complain that it's their "right" to have a vehicle that emits a lot more than the manufacturer says it should, but the tests are pretty easy to pass, and they seem to be forgetting that a car which is belching out smoke has something wrong with it, and is costing THEM money anyway.)

"Under the President’s hydrogen fuel initiative, the first car driven by a child born today could be powered by fuel cells. The hydrogen fuel initiative complements the President’s existing FreedomCAR initiative, which is developing technologies needed for mass production of safe and affordable hydrogen-powered fuel cell vehicles."
