Not sure I buy into the "no progress without the EPA" narrative. Go drive a stock 50 Chevy and a stock COPO Camaro back to back and try telling me that the Camaro isn't a vastly superior car in practically every objective measure (short of maybe high speed impact protection).

Anyway, I'm still waiting to hear from anyone on either side that has a handle on the CAA as well as any subsequent, relevant legislation or court rulings. Could be SEMA crying wolf, or it could be the EPA re-interpreting existing law in order to help themselves to authority they never had to begin with. Either is entirely within the bounds of possibility.
