the c.a.r.b stuff is interesting. As crazy as EGR backfired, there is also realms of success..only to be buried by big corporate blunders. As if noone noticed the 3cyl geo still getting restored today, or the beetle with the frictionless perfect four banger, and 3 main subes, and synchros..it is not just the electric engine killed. there is real physics in the stoich world that were killed.
the 3 main boxer is by far the most dramatic loss in ICE history.
I associate c.a.r.b with carb (carburator). Carb standard is the winner..not the california one. I always thought of it as a panic, manic half thrown together group without enough science to stand up..with that label, stuff that was truly good got killed anyway.
