Looks like the trade off is, breathing safe exhaust here, screw the rest of the planet.

26% of the US population lives in the 10 largest metro areas
56% live in metro areas greater than 1 million people
67% live in metro areas greater than 500K people
76% live in metro areas greater than 250K people

The vast majority of the US population lives in urban areas

Not just the DPF, the EGR, the injection timing program that "preheats" the cylinders with a few tiny injection pulses before the main injection events. The "preheating pulse" decreases fuel economy, reduces engine noise, reduces peak combustion temperature and pressure, reduces NOx and increases soot.

Which is why we need emission inspections in every state

Above and beyond that, there are other issues that should be discussed, but a few here would turn it political. It makes me wonder why they're here, and if they've driven people away from Ecomodder.

Wasn't talking about population density.

We absolutely don't need emissions inspections in every state. If those 26% of people want emissions testing in their mega city, then they can have it.
The 50% of people who crammed them selves into about 2% of the land area don't need dictate what the rest of the country does based problems they created.

OR has some DEQ counties and most don't. The DEQ counties hold the majority of the population. Fine by me. Funnily enough, my "mom's" car has always been registered in an non-DEQ county.

What matters is where people live not acres of land. Land doesn't get asthma from air pollution - kids do.

It isn't just the 10 largest metros that have air quality issues. I used to live in Birmingham, AL. 49th largest metro area in the USA with 1.1 million people. Horrible air quality.

The government needs to make sure it's vehicles causing the air pollution then if the people decide they want emissions testing, then let them have it.

I'm thinking emissions zones is the solution here.

You could get a vehicle that is cheaper, more fuel efficient and less of a hassle to maintain - but you can't take it in to the bigger cities.

EV-ERs could have very cheap range extenders and still go into cities in EV-mode, but they would have to be constructed such that the use of the range extender is easily noticeable from outside, so it can be policed. (Could be just that the exhaust need to have some minimum loudness.)

So you're proposing the London method of control. Wonder how that would go in a place where the decision to wear face masks is a major freaking social issue.

We already have zones in essence. In Oregon there is something like 3 counties that require yearly DEQ inspection, and the rest do not.

Give authority to the most specific (smallest) governing body capable of handling the issues that are particular to them.

The Oregon Portland Metro area requires auto emission testing because we failed national ambient air quality standards (NAAQS) for decades. As of 2017 we are no longer in violation but Oregon has decided to keep DEQ inspections in order to stay in compliance. Better to stay in compliance than be under a federal mandate and review.
