“ Few men there be who would consign their bodies to the mercy of wind and waves if they did not believe that a competent captain and engineer were aboard the craft, or to a railway train were there not an engineer and conductor at hand to look to his safety. Why should he place himself and loved ones in a motor car and start off on a trip with an uncertain hand at the steering wheel, with no one aboard competent to rule the engine, or to know if all other parts of the mechanism are properly adjusted, when a maladjustment may mean danger and even death? ”
