[quote=FlyerInHi]California was the leader in clean air. In fact, the EPA eventually adopted California rules, as have other states who implemented smog programs.
The rules are made for everybody. If you don’t like them, put your car on non-op and make it a track car.
I’m sure people remember the polluted air back in in the 80s and before. Smog alerts all the time. LA was almost like Beijing. The air cleared up in the 90s.[/quote]The problem is not in the test. It is in the psychotic belief of California’s legislators that the auto-manufacturers know how to build the cleanest vehicles. That is blatantly untrue. Run a vehicle 1/2 gasoline, 1/2 Natural gas – the car will be significantly cleaner than straight gasoline.
The other reason why smog got cleaned up in the 90’s was because the factories were required to be cleaned up. There were auto smog regs in California since 1975 (actually a bit earlier). That is partially why the 1975 and earlier cutoff.
