To the OP, I would have gotten her details at a minimum. Glad you're ok, but it seriously sucks. I find it hard to shake encounters like that.

Here in Canada, it is mandatory to call the police if the collective damage is over $1000.

Personal experience: I got rear-ended at a stop light by a small Croatian man in a Ford Econoline E250. He couldn't see over the dashboard very well and obviously didn't see me. As he slowed down "through" me, I hurdled the handlebars and my bike got sucked under the van. Taco'ed the wheel, bent the frame a bit. I was fine, but shaken. Even though I got his details, and he promised to pay the cost of the bike but, it was a real chore trying to extract the exact money out of him. A threat to take it to his insurance was enough to get him to finally cough up $850.

Through this process, I learned some things. The advice I was given was to forgo trying to get money directly from the guy and do one of two things. #1 Get your money from the other party's insurance. No guarantee as to how much you get. #2 Or claim it on your own insurance. I learned that my house insurance will only cover a bike up to $500(with a $500 deductible hah!). The only thing that would protect my current investment would be to get a rider for the value of my bicycle.
