Seminal polygonal arcade driving game by Atari. The game involved driving very slowly around a shaded polygonal track, which featured a loop-the-loop and a cow that could be crashed into. Wildly popular at the time, even though the handling was molasses-like in the extreme. It also featured a ghost car (a recording of a previous best lap) that could be raced against. It was ported to several of the 16-bit home computers and consoles. The sequel was Race Drivin'.
