Way to go, first and foremost I am thankful things worked out in your favor. You did the right thing, no question in my mind what so ever. Furthermore, I am thankful there is another person roaming the Texas roads who has been "awakened". I'll bet looking down the business end of a Kimber was one of the last things he expected. Consider this for a moment; you may have changed the persons life for the better and improved the lives many others as well. The Lord works in mysterious ways.
After over 10 years of cages I recently started riding again, I somewhat forgot how vulnerable you are whilst riding. I feel slightly safer knowing I can out accelerate/decelerate/maneuver the cages but you really are out there in the open. On a bike, every inattentive / hostile cage or road anomaly is potentially your demise unless you are 100% focused on the task at hand. A cage forcing you to the curb is most certainly a hostile action in and of itself much less exiting the vehicle.
In Asleep's situation evasive maneuvers would have probably been my first instinct, but this likely due to being under 30 <jest>and having a bike that runs all the time</jest>.
P.S. The diagram cracked me up!
