I can see it now, a Smog Inspection Station at every "Run What You Brung" weekend fun run. Must pass a $60 Smog Inspection before you can run the track, or have a cert no older than 30 days. That will just push racers back onto the streets. That's a good thing? To me it sounds a bit redundant. If a vehicle is heavily modified for track, it's most likely going to stay on the track. A couple dozen runs a weekend, during the 'season'. Slightly modified will someday have to face the inspector, so it's most likely a very minor modification, easily reversed. So you block off your EGR passageway, so your NOx goes up, it's not millions of vehicles doing this, not even thousands I would bet. It seems like the EPA is just kicking cats for all the political reasons, and not the practical ones. It's like California wanting to Smog Check motorcycles. Somehow it's gotten in their heads that motorcycles are an evil, major source of harmful emissions. Yep, the millions you see jamming up the roads, that's it! You would need thousands upon thousands of race prepped vehicles in a very small area, running all day, every day, to have any sort of regional effect. The one in a thousand truly race prepped Street Rod, Rat Rod, go fast whatever, probably shouldn't be on the road, they're loud, obnoxious, gas guzzlers, but I don't believe they have the impact "they" want everybody to think they have. The volume just isn't there.
I think about emissions something like I think about our water rationing. 'We've got to get cleaner', never mind that we've got three times as many cars on the road with one third the emissions of 40 years ago. 'We've got to use less water!' Never mind the 53% fewer gallons you're using from ten years ago, use 25% less damn it! "They" just need new targets. And a minority gets picked. A plateau gets reached, tech needs to catch up.
