Ford's self-driving cars won't have steering wheels because engineers maybe kept falling asleep

Will self-driving cars have steering wheels? Maybe not, if engineers keep falling asleep. 
Ford's self-driving cars will skip over Level 3 — where cars are automated, but human drivers are still expected to take over if need be — to Level 4, where cars are basically fully autonomous except for extreme conditions. (Self-driving cars that would meet the requirements for Level 5 are still theoretical at this point.) The levels are defined by the Society of Automotive Engineers, or
