I have to wonder how much pollution is estimated to come from vehicles, as opposed to chemical companies, power companies, manufacturing, etc. Seems its easier to put strict regulations on vehicles, which may or may not be the primary cause of pollution, and ease up on commercial enterprises.

If you are somehow implying that the government is going to "ease up on commercial enterprises," I can assure you that has not been happening. Chemical plants are under such strict regulation and scrutiny that it is difficult to even keep the doors open. Every little suspected event and every little potential event is reported to regulatory authorities and investigated in such a thorough way. Chemical plants are much much cleaner than in the past. I know what it was like in the 1990's, and the industry is significantly cleaner today.
