A modern, North American semi-truck is a substantial physical object. On average they stand 13.5 feet tall, 8.5 feet wide. With trailer attached, a truck is 72 feet long and weighs up to 80,000 pounds. It takes 400 to 600 hp to move at speed and 1000-2000 lb-ft of torque to pull it from a standing start. When the airbrakes are locked, it becomes an immense, immovable dead weight.
