In spite of California’s recent moves to the left the car culture that the state is well known for, especially in Souther California, continues to have a fair amount of influence in certain policy decisions and the aging out of smog testing requirements for cars beyond a certain age(1975 and older at this point) is one of the concessions they won. But truthfully, even in California with its unsalted winter roads the percentage of cars on the road from 75 and earlier is pretty small. I don’t think John has anything to worry about going forward.
