This is EXCELLENT news.
When these regulations were imposed by the democrat-communists, they had nothing to do with reality or physics. They were simply numbers that were designed to:
- end the production of gasoline-powered cars
- make those few cars capable of meeting such requirements tiny and all-but unusable
- make them unaffordable for average folk
- restrict the movement of much of the population.
Even a 35mpg fleet average is too high.
28-30 would be realistic.
By the way, let the "new slavery" states like California demand whatever they wish. Carmakers will either limit sales there, or... pull out of those states entirely.
