I agree with you, except for those two statements. Replace "not very smart" with "idealistic to a fault", and you're right on the $$. The ultimate goal is utopia, from the best I can tell.

Re: the second part, CARB's agenda specifically does include diesels...and getting them off the road as soon as they possibly can. I think the CARB's ultimate goal is the complete shut-down of industrialization and going back to horse-and-buggy and candlelight. I do agree with you that they've done a lot of good (cleaned up L.A. quite nicely), but as with all things, there's such a thing as "too much", and we're wayyyyy past that point...
