Hey, y’know those railway cart things you see in old movies, where two people power them along the track by hauling on levers? Well, imagine how great it’d be if someone used that concept for a car? You know you’d drop your VW Polo like a stone for one of those. Maybe.

Well, take a look at HumanCar, which uses what’s apparently called the FM-4 human-powered propulsion system, although there are electric motors on board too, if your arms get tired.
