Good point about how CARB standards have gone national, didn't realize that shift had occurred. CA isn't standing still though and will be requiring zero emissions trucks [1], which I'm not sure other states will be as ready to follow. Hopefully it'll get fleets to simply switch over.

Ya LA is still struggling mightily, especially inland. SLC metro area is a tenth of LA (1.2mm vs 13mm) and growing faster, so these forces may even out. Geographic destiny is hard to overcome.

(Thanks! I wish we could go back to those simpler times) :)
