In Campbell v. General Motors Corp. (1982) 32 Cal.3d 112, the court noted that the quantum of proof necessary to establish a design defect under the consumer expectations test could not be reduced to an "easy formula." "However, if the product is one within the common experience of ordinary consumers, it is generally sufficient if the plaintiff provides evidence concerning: (1) his or her use of the product; (2) the circumstances surrounding the injury; (3) the objective features of the product which are relevant to an evaluation of its safety." (Id. at p. 127.) The test is that of a hypothetical reasonable consumer, not the expectation of the particular plaintiff in the case. (Id. at p. 126, fn. 6.)
