Makes a hell of a lot of sense from an efficiency standpoint. Two wheels out front. Two in-line seats. Aerodynamic, torpedo-shaped passenger compartment. I'd commute in one. It would make a very sensible second car.
Just remember that both you and your passenger will need to wear helmets, gloves, boots, and leathers to boost safety, just as if you were on a motorcycle. You'll both have to switch into your suits, skirts, or casual clothes one your reach your workplace.
I only see this vehicle attracting current motorcyclists to expand what is in their stable...it doesn't have the draw to pull motorists out of a car. It would be tons of fun to try one, but I just don't think they'll make it happen in this country.
