I don't purchase vehicles that get less than 30mpg, so his crack really isn't out of line. Especially considering his Volt is a plug-in that can be in all-electric mode most of its time.

A basic gasoline sedan can still often get 30mpg, so you don't have to go to subcompacts or hybrids to get decent gas mileage.

In the context of the hybrid that he usually drives, it's pretty bad (about half of the gas-only fuel economy for a Chevy Volt, and about 1/5 of the "MPGe" rating).

20 is almost twice as good as what I apparently get, which I found out with an obd2 reader to be decently less than it's supposed to be, but I don't really mind.

What are you driving? Even my 6 cylinder sports car stays usually well above that, and my everyday Ford Focus rarely goes below 30.

1999 Jeep Grand Cherokee, v8 4.7L. Part of it is how it can only use 4wd.

Favorite vehicle I've driven so far.

I really like Jeeps too, but they give 14 mpg at their best, so 20mpg does seem good relatively, and 30mpg impossible, even if many sedans can reach it.

So you're just being deliberately daft, got it.

No, I was under the impression 20 is decent, 12 is mediocre, and 30+ is "great."
