OK, now the rest of us know what you're talking about.
California's regulations (re: clean air), have done lots of things, many of them unintended consequences. Gasoline pump prices are higher for everyone, and from what I see from afar, road congestion hasn't changed. Part of the cost of building California approved vehicles has bled over to cars destined for the rest of the country. Catalytic converters containing precious metals are a favorite target of thieves, and the typical result is that owners replace them with straight pipes, at a lower cost, and to deter further thefts. Near as I can tell they haven't done anything but enrich thieves.
Left to their own initiatives, I believe car manufacturers would have found more effective, and more practical methods of reducing emissions, and ultimately other modes of generating the power.
BTW, in and around my city, many fleet vehicles are burning natural gas, which is cleaner, and cheaper than gasoline. However, forcing all vehicles to use that, would be a nightmare installing the infrastructure, and what to do with the existing fleet of personally owned vehicles.
