But he COMPLETED the law! Which means I can ignore all the old law that I find inconvenient. But he didn't REPLACE the law, which means I can still criticize anything I think is yucky.
I think that would leave too many loopholes open. I think the most effective path would be to:
Schedule a progressive increase in fuel prices:
End subsidies on fossil fuels
Implement a tax that reflects the environmental damage caused by fossil fuel use.
Add on a tax that provides remediation of historical fossil fuel damages.
Take that schedule, add it to the purchase and maintenance costs of a vehicle, and require reporting this total cost of ownership as the most prominent figure in all advertising.
I think you're wrong about the averaging rules... This appears to be an update to the CAFE targets which average based on unit quantity across all cars and all light trucks you manufacture. You can't manufacture 10 one-off "hypermiler" sku's to offset your millions of cars.
That said, CAFE is still a worthless law that has ruined the American automobile market in more ways than one, and this policy update will likely do almost nothing to improve emissions.
