In general, being wrong makes you wrong. It makes you more wrong when you tell someone who is right that they are wrong. Soot per passenger hasn't been anywhere near car levels for over a decade. You have to go back past the 1990s to find buses that fare worse than cars on per passenger soot emissions. In 2007, diesel soot emissions were regulated to similar standards as gasoline vehicles. Stop being wrong if you want to be right.
