document updated 12 years ago, on May 15, 2010I consider "vehicle" to be inclusive of almost anything that moves across the ground. In particular, anything that can do stunts. Note that the "vehicle" does not need to be complex. Unicycles and skateboards are relatively simple machines, but they can still do some fairly complex stunts.
Some non-traditional things that I consider to be vehicles:
- shopping carts
- you can balance shopping carts on two wheels (tipped to the side, OR tipped to the back), or even one wheel (tipped to the side AND tipped back)
- you can "drift" the rear wheels
