Depends what happens when the switch malfunctions, I guess.
Failure has a lot of modes! 
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

If the ignition switch is turned all the way to the off position, then whatever equipment it is that determines whether "the wheels are turning" (as you put it) would no longer be running as well.

Not necessarily - I am not a mechanical engineer, however an electromagnet could hold the switch from falling into place when the wheels are turning(the turning of the wheels could run a small generator - on many jets the RAT auto-deploys if the APU fails and this then powers the hydraulics and essential flight avionics - it's a similar principal).

Car companies will do everything they can if it means they can save 50 cents per vehicle they sell. Do you think they're going to design a system like that?

The point I was making had nothing to do with the politics of car companies but with engineering possibilities - I am sure that 50 years ago the same argument you have just given might have been heard about airbags.

Not at all--re-read the first item of yours that I quoted. As far as I interpreted it, we were discuss the current recall for the existing cars, not what system(s) could be designed to prevent the problem from happening.

if the ignition goes off, so does the ABS, brake vacuum assistance, power steering, ...
And the airbags because when you have lost everything else, you are likely going to need the airbags..

Reports state that the faulty switch turned off air bags...So even a relatively small crash can be devastating...

Alex: Fix it? How you gonna fix this?

Perhaps we have become too dependant on modern safety devices. For example this morning on the way to work (road was obviously covered in slushy snow/ice) a driver overtook me at 80+ mph.

What happened in the US was the détente spring wasn't that strong, and the hole in the key for the ignition was off center, and, people were hanging loads of stuff off their key rings.
Result, hit a bump, the key turns to 'off' the steering lock comes on, the air bags are turned off, the engine dies, the steering becomes heavy and an accident ensues.
Moral is, don't hang all that crap off your key ring!

Thanks for the explanation, I've seen key rings on key rings on key rings with keys on each, the whole lot must have weighed between 500g - 1Kg. It wouldn't be possible to design a lock strong enough for that.
The question is how can a manufacturer be held responsible for that.
I suppose there was no statement in the owners manual saying "warning only two keys allowed on key ring"

My wife has a bunch of crap on her key ring. The key for my Mustang is just a key, no ring at all. I trid to explain it to her, but she's not having it...

Funny, my wife is the same. She has a f***ing carabina on her car keys to hang all the sh*t on. Incredible.

This explains it.
Perhaps a simple remedy is to have a weight-sensor/pressure-transducer attached to the key switch assembly beeping off when the weight exceeds a certain threshold. Wait, is this a simple remedy? Or how complicated will it be?

My car was recalled. I now only have the car key and fob on the ring. It is a pain to have two key rings, one for car one for house.
|

Ah. That's what they wanted to do with my Camaro.
But they never mentioned it magically turning off by itself, just that some people were knocking it to the off position with their knee.
I tried to do it, but couldn't. I have normal knees, not the kind with a 10 inch spikes sticking up from them, so I didn't get the recall done.

Did you just say you want one ring to rule them all?

A 65 year old woman had a heart attack and was taken to the hospital.
While on the operating table she had a near death experience. Seeing God, she asked "Is my time up?"
God said, "No, you have another 33 years, 2 months and 8 days to live." Upon recovery, the woman decided to stay in the hospital and have a face-lift, liposuction, breast implants and a tummy tuck.
She even had someone come in and change her hair color and brighten her teeth! Since she had so much more time to live, she figured she might as well make the most of it.
After her last operation, she was released from the hospital. While crossing the street on her way home, she was killed by an ambulance.
Arriving in front of God, she demanded, "I thought you said I had another 33 years? Why didn't you pull me out from the path of the ambulance?"
God replied: "I didn't recognize you."
