Given that classic cars make up a tiny fraction of total miles driven, do they really move the needle on air quality? The honest answer is no. We're talking about vehicles that come out on weekends and cover maybe a few thousand miles a year, not daily commuters. Forcing them to meet modern emissions standards is both impractical and pointless—the equipment often doesn't exist for engines from the 1960s, and retrofitting them ruins their authenticity. Exempting them preserves history without any measurable environmental cost. It's a reasonable trade-off, not a loophole.
