Introducing the Sauna Car! [VIDEO]

Because people are so awesome, we keep coming up with new ideas. Kalmer Jakobsen is one such person, and he's invented a Sauna Car. It's a vehicle that moves, albeit slowly, while passengers work up a sweat. There's a room to change, a relaxation room, and a terrace which serves as the driver's seat.

You won't be getting anywhere quick with this vehicle, but it is pretty bad ass. What would you like to see on wheels?
