Yeah, I think as the OP described it, it was the breeziness of the "Sorry" with the clear indication that she really wasn't.
Stopping, "Are you okay? I am so sorry," some indication that the driver was nearly as shaken as the rider, that's what would have been appropriate IMO.
And whether she "could have said something worse," as I've said before, it's the oblivious ones who scare me much more than the nasty ones. There are a very small few who will literally try to kill you - that doctor in LA comes to mind - but most of the ones who do something intentional are "just" trying to scare you and thus, exercising some control over their vehicle and muscles that make it likely that they won't actually hurt you. It's the oblivious ones like this - I have to say it, because her immaturity deserves it - girl, that scare me much more.
