Answer: Cameron may be barred from any recovery from Ryan if he voluntarily assumed the risk of harm associated with Ryan's reckless conduct. Voluntary assumption of risk is a defense that can be used by a defendant in a personal injury lawsuit to avoid liability.
In this case, if Cameron knowingly and voluntarily participated in Ryan's bet and was aware of the risks associated with driving down a crowded street blindfolded, then he may be barred from recovering any damages from Ryan. However, if Cameron did not knowingly and voluntarily assume the risk and was instead an innocent bystander, he would not be barred from recovery.
It's important to note that assumption of risk is a complex legal concept, and its applicability depends on the specific facts and circumstances of each case. Therefore, the outcome of a case involving an assumption of risk defense can be difficult to predict.
