You were offered three choices:
- yank on the handbrake - put the car in neutral - turn off the ignition
The "correct" answer was to put the car in neutral. Turning off the engine would lock the steering. Pulling on the handbrake would lock the rear wheels.
I'm not sure I agree with their answer.
I had this very thing happen to me - when I was learning to drive. I was going up a steep hill so I was in a low gear with the engine going quickly. When I got to the top and changed from second to third, the engine raced but I put it down to bad clutch/accelerator coordination. When it happened again as I changed to fourth, I realised it wasn't - especially as the car shot forward like a scalded cat.
I realised what had happened very quickly and also knew what would happen if I pressed the clutch or put the car into neutral, which was my first instinct: the engine would race very quickly and if it went well over the redline speed, it could well throw a piston which would be very bad news if all that fast-moving metal came to rest in an instant.
So somehow I managed very calmly to turn the ignition just far enough to kill the engine by putting it into the accessory position without turning all the way off. Had I been travelling "at 120 mph with the engine redlining" (as it said int he video) it might have been a *little* more difficult to turn it just the right amount. ;-)
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.
