In short, the numbers I have are sufficient because nothing would deviate from what is already happening.
Strange, the first part of my post got eaten between preview and submit. I posted the numbers the state used, which are based on research, rather than idle speculation like your argument.
They came up with the figure that, in the initial phase, this would save a driver $16 a year in gas, and when it's fully ramped up, $20 per year. Overall, they estimate it reducing statewide emissions by 700,000 tons of CO(2). You have a nice-sounding argument; they have the results of actual empirical testing. Even the groups opposing these rules aren't disputing that the rules will be effective, and those guys are industry pros with engineering degrees and everything.
You need to post the results of real tests rather than intellectual exercises.
Also, I'm not a resident of CA, but I am a citizen of the USA which means I can alert fellow citizens of inane regulation and allow them to act if they wish.
Sure you can; I phrased that poorly. I meant comment formally, not comment on Slashdot. The rules are open to public comments before they're set in stone, but you have to live here to do so.
But you're still a damned fool for arguing that things ain't the way they are, like the man who saw an elephant and said "there ain't no such animal". If you want to argue with the results of controlled testing, argue with the methodology, or find or perform a study that gets different results. Waving your arms and spouting theory is meaningless when compared to empirical research.
