Kyle almost lifts his left rear tire on this manuever. After accelerating to 50mph our instructor hits, at the last possible moment, one of two buttons on a box in his lap which illuminates one of two lights above the dash indicating when we may initiate braking and to which side of the obstacle we must steer. This is about as realistic a collision avoidance scenario as I can imagine and I can tell you that it produces an adrenaline rush similar to a high speed near miss.
