Yes, We Can Be This Dumb
The upcoming rewrite of CAFE (fuel economy regulations) will actually incent carmakers to produce larger, heavier, vehicles than they do today. The Truth About Cars has the scoop here.
For those who think that higher gas prices will force people to change their behavior without us having to unwind existing subsidies towards suburban sprawl and automobile use - remember to factor in the political imperative to protect GM, Ford, and Chrysler. If anything, we're likely to see even MORE counterproductive rules like these as gas gets more and more expensive. I wouldn't bet against an actual gasoline subsidy (or elimination of the far-too-low-to-pay-the-road-bills gas tax, at least) in the next few years.
Hint: STUFF LIKE THIS IS WHY WE NEED AS MANY TOLL ROADS AS POSSIBLE.
