I wouldn't be interested in the BMW C1-E at all because it is an electric gizmo.
This BMW SIMPLE, on the other hand, I would buy on the spot. Fully enclosed, actively leaning trycicle with airbags, seat belts, the height ride of an SUV, 124MPH top speed... and 120MPG. It is a personal car with the inside spaciousness of a BMW 328, where you can transport a passenger in a pinch.
