While we will never know if automakers were tipped by the EPA of this eventuality, we can definitely say that every exec in the auto industry is today dancing the jig over this news. Besides, we've been keeping tabs on this situation for some time, so we knew it was a possibility. Having multiple regulations would set back R&D spending for years, as automakers would be chasing their own tails trying to comply with multiple regulations. With no separate standard for green states like California, automakers can now build one car for all 50 states, which will save billions every year. Let's hope that the saved cash will be funneled back into green tech research and development. And let's hope that lawmakers spend more time paving the way for plug-in spots for electric cars, more gas stations with E85, and a proper fuel cell infrastructure, and less time trying to beat on OEMs in an effort to look good for voters.
