It doesn't guarantee a crash. I've had power steering failures (I've driven cars up to 400K miles). On the highway you don't need to crank wheel over so it's not impossible to hold a lane. The wheel doesn't lock if you turn car off either if that's the concern. Remember, when you turn car off you are stopping, that's your goal. With brakes you don't need to "drive" that far once car is off. Turn off car, press on brakes, done. Why is a crash guaranteed? I've driven with a car off (manual start when alternator out). It works OK (tight turns excepted without power steering)
