If you guys actually read past the headline, you would have noticed this key point you're all missing:
"Akerson said he would support a jump in the gas tax if it came instead of tighter fuel economy regulations that GM and other automakers will have to meet in coming years."
Seems like a really good idea to me. Why shouldn't we let individual people and the free markets determine what products to buy and offer versus a government regulated average minimum which invariably restricts the products a company offers. If, hypothetically, I wanted to buy a car with a naturally aspirated 7 liter engine and pay more for the gas, why shouldn't I have that option versus GM dropping it from their lineup to reach an arbitrary government mandated CAFE minimum? Do you all really think CAFE minimums are the best way to acheive better overall fuel economy/efficiency? As a free market proponent, I don't.
Give people options and make them pay for what they use. Seems like a very American solution to me.
