I'll never forget a friend who owned a Metropolitan (tiny little two-seater, not sure where they were made) carrying two bales of straw "in" the trunk. He was a starving student at the time. The trunk wouldn't carry even a single bale, so they were tied on. I've seen photos of French farmers carrying calves in the trunk of their little sedans. They didn't say they had the scours, but, it really doesn't matter much with a calf. I've never seen a photo of a scooter carrying calves, but I have seen one carrying a family of 5. Likely you'd do what you have to, depending on circumstances.
To bring this back around to the subject of the forum, George B. of Utterpower seems to like the Chinese two-wheeled "tractors" with diesel engines. Seems like it would be possible to make a low-speed vehicle with brakes, lights, etc. that would easily haul typical loads for short distances but still be inexpensive. May be the wave of the future. If the powers that be could create incentives for such a thing, (cheap licenses, insurance, etc.) it could happen pretty quickly.
