You would have the "cost of maximum compliance", but you could also have the "best MPG" in low density (i.e. agricultural) areas. GM already has OnStar, so the hardware is already in place.

PS - I'm not sure I would advocate this is a real-world solution, but I think it's technically possible.

Since there are only two standards I'm aware of, Fed and CARB, I don't see why it wouldn't be possible, but both require DFPs so it's not like there would be less equipment, and significantly better mileage. We're talking about a year or few of lag between Fed and CARB emissions standards. What's gotta happen is the advances seen in gasser emissions management for diesels. They're where gassers were in the 70s, but fortunately they have a bit more in the way of tech to apply. Unfortunately, this means we just see higher tech cludges, instead of research on comprehensive emissions control strategies, like we see in gassers these days.
