Wow, just reading about your mishap created knots in my stomach. I go down a very steep hill on my commute home and it is plagued by people making right and left turns in front of me. I too, try to be as careful as possible, knowing that at anytime, I could be hit. Once I am down the hill, I have found, for my safety, I ride the sidewalk in this short stretch till I can get to a side road. Everyday there seems to be a new "challenge" that has presented itself. I am glad you were able to stand up after your collision and that your bike is ok.
