How about SUV buyers perfectly happy with terrible mpg, terrible sightlines, multiton curb weights damaging their roads and driveways, built too large to fit into parking spots, and driving like maniacs with their supercharged v8, never once using their blinker? Those people seem content. Still, their choices lead to certain externalities we all now have to deal with to support their "big hulking car" syndrome, wherever it comes from (compensating perhaps).
