I had a fully faired trike 20 + years ago. Inherently more stable then the two wheeler. Even with two of the NACA low-drag air vents I got dangrously over heated and dehydrated in the spring going from Las Vegas to LA, and again from LA to Northern California. Last generation, true but it ran 68 pounds trike and shell combined. Add in 30 lb of stuff (it was a tour) and it was a drag up hills. Trying to commute with it in Colorado the clear bubble dome would frost over in seconds in mid winter. Now I use a touring bike for commuting. In 1983 dollars it cost $2,300.
