a LORRY is a little truck like a U-haul or an Isuzu. It goes “beep beep” and the driver waves at you merrily as it passes by.
a TRUCK is a gigantic box on eighteen wheels. It goes “Honk honk” and the driver glances at you impassively from their perch high above you, as you are brushed off the side of the road.
a SPORT UTILITY VEHICLE is a truck if it carries cargo, a car if it carries children, and REALLY AMERICAN if it has a dog riding in the cab.
a HUMVEE is a brick on wheels that handles about as well as a literal brick with wheels.
YOU are bicycling on the side of highway for some reason.
