You have learned something. The time between when you recognize the danger and react to it is all the time you get , period. What you do in this time can make the difference between rider and rag doll.
I've slide under 2 cars, slid across the hood of one other, and have been pushed off the road by oncoming traffic twice, and ran into a German Shepard. In all of these events, time was slow as it happened, can't explain why.
Each time I was in full leathers ,gloves,boots and helmet and it still hurt allot, leather gets torn up and gets hot too you know and does nothing to absorb impact .... I never slid off the road surface and got into the trees, signs or guardrails, you don't want to do that. My good friend did that, didn't have a chance, we buried him at 18 .
The last time I remember sliding behind a spinning bike, I caught up with it and laid on it till it stopped. Always slide on your butt facing the direction of the slide, so there is a chance to maneuver away from objects, never head first if you can help it. And contrary to the kung Fu idea that rolling with the forward motion will slow you down and deflect energy by not absorbing it....that's when bones get broken.
I always ride by the tenth of a mile , what I see in front of me has an escape scenario, when there 's traffic it's multiple trouble and multiple escape scenarios. It's all about survival first and the spaces in between the thought process is the enjoyment and thrill of the ride but, most folks won't realize the thrill until the kickstand goes down.
The fact is that you must be prepared for evasive action at all times, it's not for everyone , that's why those who ride are special.
