Is there insufficient evidence to support plaintiff's claim that the design of the horn cap was defective?

Defendants claim that there is insufficient evidence to support the following three factual ingredients allegedly essential to plaintiff's case: [17 Cal.3d 367] (a) That the design of the horn cap was defective; (b) that plaintiff's jaw in fact came into contact with the center hub area of the steering wheel after displacement of the horn cap and exposure of the underlying prongs; and (c) that plaintiff's injuries were aggravated due to contact with the exposed prongs in the center hub area of the steering wheel. We view the facts in the light most favorable to plaintiff, giving her the benefit of every reasonable inference and resolving all conflicts in her favor in accordance with the standard of review long adhered to by this court.
