John,
I think where we differ is that you see this ruling as just applying to this particular case involving this woman who dragged her friend from a wreck; that case has now been cleared to go to trial. I see this ruling as precedent that essentially erases the Good Samaritan law wrt all rescues. This ruling was from the CA Supreme Court so it applies much more broadly than just the case at hand. As a Joe Citizen, this tells me to not get involved at all. Since you're a professional you may have a different view.
