Firebeetle tried making a Carousel of Doom arena, where you fight to stay on a spinning merry-go-round, but unless you set the floor friction to the point where you can hardly drive, the floor just slides underneath the bots and the bots don't move. And if the friction IS that high, the floor has to be spinning at a snail's pace or else the centrifugal force will hurl all the bots off before you can so much as say "It doesn't work."
