Glad that the damage to your body and bike was not worse. It sounds like it could have easily been a lot worse. The randomness of it is really frightening. He (and I assume it was a he) was probably drinking or on drugs and showing off to his passenger(s).
I am and older rider and still love to ride. Did a 230 mile loop ride yesterday on my gsxs (love this bike). But I have made a decision that I will not ride at night. The average car driver's skills are poor at best and the probablility of impairment is greater after cocktail hour. Plus I think that darkness tends to bring out the ******* behavior in assholes.
