[quote=XBoxBoy]Please tell us, what are the advantages of regulation over taxation?

I never said that regulation was better than taxation. Taxation is probably better because it would start inhibiting demand immediately. My guess is the environmental groups don’t push for increased gas taxes because they know that the public won’t support it. So they go for the next best thing which is increasing the CAFE standards.

I’m in favor of anything that will inhibit burning of fossil fuels, so I support both increasing the CAFE standards and increasing the gas tax. Unfortunately, I’m likely in the minority on the gas tax increase and thus have to live with the preferences of the majority which is no gas tax increases.
