It's a Shopping Trolley on Steroids

Okay, it's a compact "stackable" environmentally friendly automobile developed by MIT, but you can see where the analogy comes from. It does hold view to being a form of "common transport" ina similar system to say trolleys at the airport. Come along, take the first compact off the line, and park at the end of the line when you return. I saw it in some dystopian film, sure they turned out to be evil Nazi wannabes, but environmentally friendly ones.
