Why you so against emission tests? California is one place where its benefited no end.
Against testing or against over regulation that does not fit a situation that warrants it? As far as I am concerned where air pollution is actually bad they can test everything they want to make sure it's up to spec.
The thing is, california has air pollution issues in a few of its larger cities due to their excessive populations plus geographical and local atmospheric uniqueness that tends to trap the localized air in them for too long thus allowing the pollutants to over accumulate to where they do become a problem. There that level of regulation is more than justified.

However, where I live we do not have that combination of high population and atmospheric stagnation problems (2nd cleanest air in the country!) and thusly that level of regulation and enforcement of vehicles, farming, or heavy construction equipment emissions systems is unwarranted here. AFAIK, heavy commercial trucks are the only thing randomly spot checked to any degree here and even then they are pretty light in the amount of checking they do plus most people who do get checked over and fail simply get a 'fix it' ticket warning telling them to take care of their malfunctions.
Unless you got caught 'rolling coal' in a obviously modified heavy commercial rig multiple times the odds are you wont get much of a ticket here.
So, as I have stated many times in our discussions.
I am not against reasonable environmental protection policies and actions where they can be proven to be truly justified in a specific area. I'm against heavy handed obvious power/greed driven blanket policies that over restrict people's actions, in the wrong locations at the wrong times, or that do not warrant the regulation to the levels forced on them without fair and justified cause based on various local conditions at the time.
Rather like speed limits. There's a reason that residential areas have them set a 15 - 25 MPH and some places less, yet open interstate is 75 - 80 MPH standard One location justifies the far lower standards (for multiple reasons) that the other does not.
Where I live is environmentally largely the equivalent of the interstate (wide open spaces with high natural airflow, large vegetation footprint and low population) regarding air pollution. We cant run unlimited here but we can run pretty light on the regulation simply because the environment and us people in it are capable of easily handling it.
That's why I am a strong advocate for local control of environmental regulation and strongly against federal level blanket type regulations based almost entirely on blind to reality based - worst case/what if - scenario situations that the bulk of the the nation does not have to deal with, or likely ever will have to deal with, themselves.
