I'm glad to hear you and your family are OK.Opening a car door into traffic is a violation, usually $20-30 (depending on the city).  It more often causes injury to bicyclists (who refer to it as getting "doored") than cars because the latter are much larger and noisier.  Nonetheless, when talking to the police and insurance company, repeatedly emphasize that the other driver illegally opened her car door into traffic so that you don't get stuck with any of the blame or liability.
