"I find it difficult to believe that the seat belt can afford the driver any great amount of protection over and above that which is available to him through the medium of the safety-type steering wheel if he has his hands on the wheel and grips the rim sufficiently tight to take advantage of its energy absorption properties and also takes advantage of the shock-absorbing action which can be achieved by correct positioning of the feet and legs."
-Vehicle safety engineer for General Motors, 1954.
