I was 37 the first time I lived somewhere that had mandatory emissions inspections. I think the states I lived in previously waved them if your car was newer than a certain date. I always thought they were a fucked up kind of poor tax. "What's that peasant? The car you need to survive in our car centric wage labor society is old and busted? Fuck you, your car is not verbotten, but we're also not going to provide a working public transit system".
