CobraEd, it is all about the money - the money that the Feds give CA for hiway/road maintenance is all based upon CA meeting clean air standards. With CA leading the charge for more strict emissions for new cars, I can't see anyone standing up in front of the legislature promoting smog exemptions - they will be laughed at. For these reasons, I am not surprised that no one is trying to create CA legislation based upon the SEMA model (disappointed, but not surprised) -
