America hasn't cornered the market on ungrateful bitches; we just enjoy the freedom to file seemingly frivolous lawsuits (note that the court only ruled on the liability protection of the Good Samaritan law, not that the do-gooder was negligent). Without further evidence, I can't say if she was careless or not, but unless the car was on fire, she should've left her immobile (everybody knows not to move a person with a potential spinal injury).
