Am I right that the last thing you want to do is let the engine greatly
exceed its redline speed and risk it seizing up (I'm assuming that the
car
is old enough not to have a rev-limiter)? Do any steering locks actually
lock the steering while the key is still in, even in the off position? I
thought it only locked when the key was removed - for this very reason,
so
you can safely turn off the engine in the event of an emergency.

A modern engine under ecu control will not exceed the redline, unless
there is some outside influence.

The outside influence being either going down a very steep hill and
heavily laden, or a diesel engine which has begun running out of control
on its sump oil. Ignition switched to accessory (I) should work to kill
the power from the engine, apart from a run away diesel. Hard on the
footbrake should slow the car plus engine down.

If in the case of a run away diesel engine you cannot slow down enough,
clutch down, into neutral brake and let the engine self destruct.

How would the sump oil find its way into the cylinder? Via leaky piston
rings? I presume top gear and hard on footbrake *should* stall the engine.
