What i don’t understand is how fuel efficiency does not seem to be a concern of an average buyer? It is a large factor for me, and I’m proud to have highly efficient car for its class. Are those large trucks somehow more efficient than older, smaller models? Or are average buyers just not concerned with efficiency?

Well not everyone has seen the light of factorio, so i might be over-fixating on efficiency.

Full size trucks can get about 22 mpg highway. A 2011 Ford Ranger, the last year they were made, got 19 highway, with the v6…

They have gotten more fuel efficent.
