I agree it is a LOT easier to build and title a motorcycle then a 4 wheeler.
The Aptera claim was something like this: "...and of course three wheels have less rolling resistance than four." That's incorrect, unless they are saying that the vehicle is lighter, and therefore has lower rolling resistance.

Three wheelers (aside from the side car arrangement) pick up the additional frontal area of the third wheel, whereas the rear wheels of a four-wheel car are in the wind shadow of the fronts.
