Tighter emmisions standards

Ok, you got me there. I did not think about planet Kalifornia. And about the cleaner air in California. I visited my sister who lived in san Diego back in the mid 70's. On the way back I had to go through LA. No bull here, but when we descended into LA, you could see, literally see, when we went through the layer of smog. That reddish orange stuff was not nice. But it's too bad when the state wants you spend way more money than is necessary to comply with the law.
