A tiny electric car can be great for a ton of things: Saving money, helping the environment, finding parking spots, and grabbing looks from intrigued pedestrians. It also has it's downsides, though. You can barely fit a backpack in one of those things, you can't take long drives, and there's a constant fear that you might end up like one of those smashed cartoon characters plastered to the pavement after an accident. 

Rinspeed is trying to eliminate some of those issues with its newest modification called the Dock+Go. It's basically a slip-cover that adds a "bed" and third axel to your midget vehicle, giving it more space and the opportunity for another battery, fuel cell, or gas generator. It's a nice idea and all, but is it worth the extra purchase and effort?
