Sorry to hear of your fall, and good that your ok and bike is not so bad... i know hindsight is great thing, but in that situation i would of just used the rear brake and kept the bike as verticle and straight as possible, i know it would of ment maybe (probably) hitting the cyclist but chances are your momentum would of kept u upright and then you could of pulled over, and he was at fault (sorry is not going to help if you had been hit by the car!).. like you said, there were cars following you, and say the car driver was changing radio station or something and didnt see you fall to stop in time, it sounds selfish/irrisponsible, but we bikers gotta look after number 1 and hitting a cyclist will hurt less than being run over by a car, this is from experience.. same applies if an animal runs out in front of you, best is not to brake to hard as the speed will keep u upright. there are many vids on youtube etc of sports bikes hitting large animals and their speed kept them upright.
At the end of the day tho everyone is ok and thats the main thing. Sorry for my little rant but angers me to see a fellow rider go down hard through no fault of his own!!
Ride safe all
