Donzo, as a certified chief instructor in a motorcycle training program, I must take issue with your statement that you "had to drop and slide your bike." No one, and I mean no one, has to drop their bike. What you are really saying is that you lost control of your bike. Dropping and sliding are not evasive maneuvers. Rather, they indicate that you had no control over the machine. A trained rider will remain in full control, using maximum braking, right to the point of impact if necessary. You can either swerve to avoid the problem, or brake, but with a two-wheeled machine, you should never attempt to do both at once. If you decide on an emergency stop, scrub as much speed off as possible, but under no circumstances should you "lay 'er down". This way of thinking is an archaic holdover from the 1930s and 40s, when motorcycles had woefully inadequate brakes.
No one "just pulls out in front of you". Using the "Scan, Identify, Predict, Decide and Execute (SIPDE)" acronym will allow you to identify threats before they are in your path. Constantly scanning and identifying predictable threats is the stuff of life of motorcyclists and Spyder riders.
I am sorry, but not surprised, that you were badly injured. This is to be expected when you hit the pavement in the manner you have described. I regret to say that what you have described is the result of unskilled - and I am guessing here - probably untrained, riding. :dontknow:
