But as the video points out, people don't associate a 2mpg difference with a very drastic improvement in fuel consumption.

My guess is that we mentally categorize the two as 'gas guzzlers' or 'abysmal mpg' without doing any math.
Maybe we mentally categorize the two as gas guzzlers because they ARE gas guzzlers. Going from 14 mpg to 16 mpg just restrains the guzzling a bit. The point is to go from 14 to 40 mpg, or 16 to 60.

And oil change intervals of 3000 miles? Even my '88 Toyota pickup specifies 10K miles.
