I rode one on a recent company sponsored test ride, which lasted approx. 1 hr. through various road types, highways, backroads, and city traffic. The handling is phenomenal, although much different from riding a two wheeler. It takes a few minutes to break old habits, such as leaning into turns, getting used to not having to put your feet down when stopping, and overcoming the sensation that it's going to flip on sharp corners or curves (which is isn't because of it's suspension and design), and you start enjoying the ride for what it is.
I'd seriously consider one, when I'm no longer able to ride a two wheeler, because of age, or physical limitations.
