Note having 2 wheels in front and one in back is much more stable, since most of the time you are moving forward, not backwards.

The Reliant Robin (British, 70's) had 2 in back and one in front, and was reputed to have stability problems. On first viewing one the immediate question that came to mind was why bother building something like this???? >

Anyway, sooner or later every discarded concept will be resurrected......
