Rinspeed has been dreaming up insane vehicles for years -- from scuba cars plucked from James Bond's garage to modded self-driving rides. Even if they never make it to the public, the concepts are at least fun to check out, and the Rinspeed Snap is no different. Essentially a modular vehicle in two parts, the Snap is made up of interchangeable pods that attach to a rolling chassis, which houses data-processing computers and the EV power train. When the latter starts ageing, you simply slide a new one under your existing pod, theoretically extending the lifecycle of the vehicle at a fraction of the cost of buying a new car. And, if you get bored of the top half, you can swap that out too.
