Can't disagree with no lead and catalytic converters. I remember driving through our local small city in the winter. Cars with bad carburetors were dumping raw fuel fumes out the exhaust pipes. Cars with bad rings were leaving a fog behind them. Slow traffic could make your eyes water at times. Prior to that, I don't think there were any automotive exhaust regulations. Air quality here has been great the past ~45 years. Yet they continue to tighten up the emission standards - and the price of cars goes up and up.
