Thanks for your informed commentary, but what I want to know is “emitting 40 times the allowed NOx poison” really a problem. My experience is with lead where lead poisoning in children was dropping precipitously under the old standard and when the bureaucrats saw that they arbitrarily halved the lead standard per liter of blood and viola: number of children with lead “poisoning” sky rocket.
