I'm not sure how that would have played out, and that is an interesting question. I know that if my ride had suffered any damage at all, even a scratch, I would have stuck around until the police arrived and would have been a part of the accident report/investigation process.

I will throw this thought out...when I placed my bike on that rack, I did so with the reasonable expectation that I would be able to retrieve it at the end of my commute. Although the bus driver was clearly not at fault, whether I would have any recourse against the bus company if my bike had been damaged is a question I have been wondering about and am unqualified to answer.
