So because Americans are incredibly short sighted and continue to buy vehicles which waste fuel we’re going to chance the standards for the future? That makes perfect sense.
There’s a pretty easy solution to the problem of consumers being stupid and buying big trucks and SUV’s: you tax them. Start another cap and trade scheme with cars. Use the taxes on vehicles which aren’t efficient and use that to offset the effects those cars have on the environment. Use the taxes to create subsidies for solar panels for low income families. Use it to increase rebates for electric cars. Use it to fund better mass transit.
Do SOMETHING other than giving up because you’re a bunch of short sighted idiots.
