Tango Charlie's sketch made me think about adaptable vehicles.
The problem is most states don't permit riding in trailers (9 allow it). What about a vehicle you could connect that would become part of a larger vehicle that you pushed? I saw something like it this summer. A PWC that connects to a larger boat to provide the power. It's called a ShuttleCraft:
So, I've been trying to figure out how a small vehicle (motorcycle or sports car) could dock with a larger vehicle to provide the propulsion.
Ideas?
Question Part 2:
If your state allows riding in trailers, would you put your family in one?
