Then directly subsidize cars that are smaller and have lower displacement engines. CAFE is just a really ass-backwards means of achieving your stated policy goal. Plus it's not doing a damn thing to change consumer behavior. Having Congress decree a technologically unfeasible MPG standard won't make someone buy a Honda Fit rather than V8 Camaro. CAFE leads to rednecks building "coal rollers," giving them taxpayer incentives to buy small cars means they'll consider a 1.8L small sedan for reasons of economics.
Want to provide any empirical analysis that says CAFE standards have no effect?
