In the instant case, the plaintiff was ejected from her car, which subsequently rolled over her body causing a broken leg.The defense expert stated that she would have remained in the car had she used her seat belt, and that she would have sustained only minor injuries had she not been ejected. On cross-examination, plaintiff's counsel was unsuccessful in his attempts to undermine either of these opinions of the expert. In view of what has previously been stated, we hold that the trial court properly submitted this issue to the jury.
