After my [70826 - Flipcar], the idea stuck in my head. All you really need to do is have the wheels big enough, and figure out the height limit (2 plates, in this case). So at 24 fairly basic bricks you get a studless, sturdy design that can roll on both sides, fall of tables and chairs and keep going.
I have also built a 3-level [track] for this car.
Go nuts with the colors and send me some pics :)
