In the LX Month Competition Current Standings website - http://competition.lfs.net/lx_autox/ - there is an unnamed column to the right of the Lap Times column. It seems to contain only "w" and "m". What do these represent?
That's the controller the driver was using. w - wheel, m - mouse, ks - keyboard stabilized, kn - keyboard not stabilized (i think that last one is right).
