The rules assume that a skitrack has two tracks and two skids. Going
from that to one track and two skids (or even one ski) is one thing, 
going from a tracked vehicle with two tracks to one is something 
else. 

With one wide track and one wide ski, the track is propulsion and 
the ski is steering. With just one track, the track must steer.
