1. X was injured while he was a passenger in a bus operated by Y Co. The proximate cause of the accident was the failure of the steering knuckle to work causing the driver to lose control of the wheel as a result of which the bus fell into a ditch. Can the operator now relieve itself of a liability by claiming that the real cause of accident was a fortiuitous event? Suppose that the proximate cause of the accident was a tire blowout, would that make a difference in your answer?
