There was another similar thread here recently. IIRC, the person who recorded the video was advised by the police and/or insurance company to not post the video publicly at all, or at least to pixellate identifying information like faces and license plates, for various plausible-sounding reasons. These included (from memory) the risk of extra-legal retaliation or harassment; the risk of a lawsuit (even if the plaintiff were to lose badly in court, being on the receiving end of a lawsuit would not be fun); and complications in getting the claim for damages for the current incident resolved.
IMHO, public shaming on a national forum (even one with limited appeal, like this one) for something that barely qualifies as a fender-bender is a bit dubious. Peoples' lives have been ruined when things like this have gone viral. Yes, the driver in this case didn't do the right thing. If the video were to be Tweeted publicly and go viral, though, she could conceivably suffer serious consequences, like losing her job. That might be OK if her job were as a valet or taxi driver, but not for most people. Worse, as noted earlier, there's a child involved who was blameless, and exposing the kid to this sort of thing is not cool. I understand the desire to extract a pound of flesh for damage done to a valuable asset, especially when the person doing the damage seems not to care; but the Internet can randomly amplify messages that spark outrage beyond the realm of reason. Thinking a bit before unleashing that beast is worthwhile.
