> How about this: fleet efficiency standards are stupid, anachronistic and counterproductive. Scrap them. Then, separarately, create a consumer-side rebate based on a vehicle's mileage. (Because a gas tax breaks American brains.)

It's a good concept that is also ripe for abuse with anyone who has some amount of "fuck your rules" money. Same reason why fines that don't scale with income/earnings in some form often do nothing to deter "the rich".

I certainly like carrots more than sticks, but we need a couple of sticks as well.

Scaling fines with income only works to hard stop behavior, at which point just make it illegal. Most fines are proportional to damages.

Criminalizing fossil fuels is insane. The fines should cover the externalities.
