I could not agree with you more. I was in China last year and I could tell you stories.. They have some huge pollution problems. When it gets warm in Guangzhou and the bugs come out... one common way to get rid of them is to fill a 5 gallon metal can with old motor oil and light it.. That makes a nice blanket of black smoke to keep away the bugs.. and it works well in the city! Shopkeepers were doing that! 8-O I'm not kidding. LA is not far behind. They really screw up things for the rest of us in the US. We now have to tolerate California approved gas/petrol (CARB approved) cans that have "California approved" nozzles that are almost entirely unusable. Borderline insanity! You could not pay me to live in LA. I was doing some work for a major manufacturer of catalytic exhaust system for diesels. They supply just about every auto/truck company around the world. They told me that they have no idea how they are going to meet the emmision standards that exist beyond this year. All of the current tier diesel engines have filtered exhaust systems. The exhaust is passed through a ceramic filter to catch virtually all of the particles and then it is run through a catalytic converter. The diesel exhaust system for one major brand pickup truck in the US that I was working with had a retail value of $3500-4000.. When those trucks get to the midwest USA, it is very common to cut all of the pollution controls out of the exhaust system and reprogram the engine controller to ignore the missing sensors. The result is that the horsepower and mpg goes way up.
