If four people are involved, the car can run on human power alone. With one driver the vehicle would have to employ the use of the included plug-in electric engine (in either hybrid or full electric mode) in order to maintain street speed. The engineers, however, would like to add that this is an exercise-enabled automobile, and as such it’s much more than a mode of transportation — it’s also a way to get in shape.
It’s cute, but the video looks like it’s hard to navigate, and keep in the lane. Making the steering and pull lever the same physical thing I think is a pitfall. Maybe if they made the driver’s charger a clutch-pedal it would be better?
