What are you trying to achieve? You're ok, the bike's ok, the driver apologised. If you don't have any witnesses it is your word against her's. What do you expect the police to do? And, really, why waste their time and your time with it? I can't see what you have to gain?
Nah waste of time. The 2nd, 3rd, 4th person they hit won't have a problem as no driver would plea "oh noes, this has never happened before it's an accident".
