From what they were reporting on NPR yesterday ... California has to ask Congress to extend the exemption every year.
So it's not up to the President whether or not CA can use higher standards, it's up to Congress.
As I said ... it's odd, because "exemption" usually means the state has a LOWER standard.
But in this case, it means the state has a HIGHER standard.
Personally, if *I* were in charge of a car manufacturing company, I'd stick with the original standards ... or better.
I mean, if one President can "delay" the standards what's to stop the next President from "speeding up" them?
The main problem with the mandated fuel economy standards is that the least expensive way for automakers to comply is by making vehicles lighter.
Replacing steel with aluminum and fiberglass is cheaper than re-engineering already highly fuel-efficient engines. In fact, that may be the only way to meet the latest rules, according to the National Highway Traffic Safety Administration.
Lighter cars and trucks are less crash-worthy than heavier ones. Stricter mileage standards therefore will lead to more injuries and deaths on the nation’s highways.
