Hard braking and swerving tend to be mutually exclusive> manouvres - did Hurt draw any conclusions on which one is generally preferable?Apparently the instinct to brake in the face of danger isn't as strong as the instinct to freeze up and do nothing in the face of danger.  Hurtfound that a surprising number of accident-involved motorcyclists hadn'tused their brakes at all prior to impact.  I think the only way you'll ever use countersteering reliably and correctly in a crisis is to make it the only conscious method of directional control youever use, and to practice it constantly, even when you have no need to doany turning.  If you follow me down a long straight, and I seem to be wiggling back and forth randomly or suddenly without obvious need, it's becauseI'm practicing countersteering and avoiding imaginary obstacles directly inmy path.  All of this practice may indeed be futile, but if I have evenmilliseconds to react, the most *familiar* tactic available (and hopefully the most automatic) will be countersteering.  The same logic applies to brakingwith the front brake, of course.Chuck Rogerscar377@torreys.att.com
