>>>If you're on a winding mountain road, with vertiginous drop-offs, and some villain has severed your brake pipes, don't bother trying to pump the useless brake pedal and steer around the vicious bends; just reach for the key and turn the damn engine off. Engine braking will then slow you down and eventually stop you, esp. if in a manual trans. car.

>>Too bad most cars have a mechanism to lock the steering wheel when you turn off the engine.

>I had that once when the engine stalled just as I went round a very sharp bend on a very steep hill. Instantly no power steering and no brakes. very exciting.I think if my wife had been driving she would have gone over the edge as it required a lot of strength to turn the wheel and get any braking.

Last year I had some problems with my car which sometimes made it stop in idle. It was very scaring when my car stopped a few times when I drove down a steep, winding hill. With automatic transmission I could not easily increase the RPM, but using a lower gear helped. But when the car stopped in the next very busy intersection when I wanted to make a jump start into the busy traffic, my heart almost stopped. So when I came back home I persuaded my garage into giving my car top priority.
