Keeprite is the beginnings of a game where the object is to pass other cars while staying out of the way of others that want to pass YOU.  (We're all cooperative drivers now aren't we?)  Basically all you can do in it now is change lanes by pressing the right and left arrow keys (watch the rear view mirror) or change the speed by pressing the up and down arrow keys (watch the speedometer).  As an experiment try hogging the right lane for a minute.
