With the economy at best slowing its wobble (and reason to be wary even about that), the Obama administration has added requirements for “better gas mileage for cars and trucks and the first-ever rules on vehicle greenhouse gas emissions” to its list of desired drags thereon. Note this now-familiar feature:

The proposal will cover vehicle model years 2012 through 2016, allowing auto companies to comply at once with all federal requirements as well as standards pushed by California and about a dozen other states.

Now, I’m sure there are a whole lot of arguments that one could put forward, with respect to time for such things as research and marketing plans, but a growing fist of expensive programs seem slated to swing by during the millennium’s teens — after the next presidential election.
I’d also highlight this:

The administration estimated the requirements would cost up to $1,300 per new vehicle by 2016. It would take just three years to pay off that investment, the government estimates, and the standards would save owners more than $3,000 over the life of their vehicle through better gas mileage.

Except for the fact that gas will increase in price as it adjusts for the lower demand…
