Traditional Australian utes were just passenger cars with the back chopped off. So they had the same footprint as passenger cars with the same safe front style and efficient practical design. Then the American pickup trucks arrived, stole the term "ute", and now proper utes are extremely rare.
Aussies created the category of vehicles with trays. Ute = UTILITY VEHICLE.
Yanks fucked it up and morphed it into "trucks" - the monstrosities of emotional support vehicles you see today.
