Damn man, I got hit by a car today too. :< I was on the sidewalk carrying a 20lb bag of rice in one hand and looked back to go on the road and the next thing I knew i was bailing over a car. Guy popped out of an alley. Luckily my bike is fine minus a bent clip and the bag of rice didn't break.. my shin isn't diggin the situation though.
Sounds like you handled it ok except maybe flipping on him but I can see how you could be freaked out. Enjoy your new bike and at least your not dead or broken.
