On a number of ocassions, have I personally witnessed cruiser riders being beset by partial emergency situations in traffic, whereby the rider jammed on his or her back brake, locked up the rear wheel, and proceeded to low-side and slide down the road on their ass, into whatever object it was that they were trying to avoid in the first place (apparently such was the case on the STS the other day, as well) ... but where there was actually plenty of escape opportunity available to said rider, had he or she taken cool thinking corrective action (either better braking and/or steering inputs).
So I gotta ask - why didn't said rider apply more FRONT brake? Or why didn't said rider release some pressure off the rear brake, and then re-apply successively increasing pressure, to a maximum traction/friction point?
I know, I know - panic/freak-out in the moment, lack of skill and knowledge, lack of rider training, lack of understnading of the physics of it all ...
However, to me, there appears a greater issue. Why is it, that people who don't have a clue how to re-act in emergency situations, get licensed to barrel around on the road?
