Honda Goldwing Retriever is an amazing vehicle; it is a motorcycle that can tow automobiles. I can’t believe I’ve never seen these before, as this article is 5 years old.
It’s a Honda Goldwing with a foldable towing rig that rides through traffic like a normal motorcycle, splitting lanes and weaving through the jam until it arrives at the scene. Then it unfolds the towing rig, loads up the car and rolls away. The Retriever’s towing rig carries the weight of the car on three wheels so the motorcycle can still be ridden normally. Since the motorcycle is only providing the torque necessary for towing and doesn’t have to carry extra weight, the vehicle is easily moved and a six cylinder Goldwing has all of the power you need. The Retriver can tow cars up to 5500 pounds.
This page shows a Retriever in actual use in Japan or China (comments are conflicted about the location).
