The amount of pollution from individual private cars is nominal, but the amount of pollution from cars en masse (especially in concentrated road structures like highways) is substantial[1]. It becomes even more substantial when you mix in commercial car (read: diesel) traffic[2].

The GP talked about outside his house, not highways or business districts.

If you live on an interstate, and don't want to, the best course of action is to move.

Sometimes you don't live on an interstate, but the interstate moves next to you anyways[1].

Other times, you live in a beautiful residential neighborhood (like I do), but 18-wheelers drive through your neighborhood and idle next to the public schools because there's no enforcement and it's convenient.

A surprising statement like this needs a reference or citation, some sort of explanation as to how you came to believe it.

He got a high from breathing straight from the exhaust pipe. Then the Lord appeared to him and said, "And you shall make it known, on HN, that the exhaust pipe is not the enemy, but the friend."

I get that you don't agree, I just think it's a shame that you're not clever enough to articulate why.

There is nothing to articulate or to "agree to" here. Just read the basic facts.

Clearly you’ve never been to California during an inversion.

Well, that's a different set of circumstances, where you've got a lot of very badly-made cars with ineffective emissions control systems running on very poor-quality fuel.

Cars can never be failed, only liberal governments can fail them?

You sure about that?
