Well, when they start making cars FBW, I'll quit driving too !
Better stop driving now then.
All my recent cars have had electronic throttles. They also have power steering, and without it I doubt I'd be able to turn the wheel unless I was already going quite fast (I don't fancy the idea of driving a 2.5 ton vehicle with failed power steering).
I'm sure older cars without power steering are rigged differently. Modern cars are heavy in comparison (I'm fairly sure it is more than just being used to power steering - I'm no lightweight).
Back on topic: FBW or no FBW - it took PILOTING SKILLS to put that A320 in the drink in almost one piece. FBW merely made moving the flight controls easier, protections or no protections. Would Direct Law have helped? I'm skeptical it would have made any difference at all.
Mech backup however...
