The devil is in the details. There are many production cars currently driven on the streets whose owners have modified the intake and timing systems (supercharged, injected, etc) to use them on the track on the weekends. Whether or not and how the EPA chooses to enforce their regulations regarding the use of these vehicles on the public ROW is a matter for concern. There are some jurisdictions like CA where these vehicles might not pass the SMOG testing and are limited to use on the track only. IMO if the EPA had its way that would be true on a national level. SEMA has blunted the attempt by CA and other local agencies to regulate the emissions from our vintage iron and I applaud their efforts to challenge the EPA on this point.
