Another way to deal with this in addition to vehicle related pollution and safety issues is a good technical vehicle inspection program through the state DMV to get or renew the vehicle registration.
I would mind less smogging my car every two years if I thought it actually made an impact on this at all. I just wish police would actually crack down on these sorts of crimes. But I get the feeling that a lot of them are the same ones driving Harleys and Chargers.
