Random idea. Change emissions requirements based on GPS coordinates. That's sort of what they do in shipping. Ships burn cleaner fuel in port. If a semi is driving around Los Angeles low emissions are important. In middle of Kansas not as much.

That said phasing out diesels is better idea over the medium run.

That kinda happens as vehicles that can’t pass emissions get exported to states/areas that don’t have the testing.
