Haven't you ever tried this before? I have. Hehe.
If you're in an auto transmission, when you turn the ignition back one step while you're still moving in gear, it just turns off the engine. The engine is still turning, but no power is being made. I don't recall how that effects the steering and brakes, but the steering would not lock up (maybe harder to turn though). I don't think the steering wheel will lock unless you are in Park.
When you're done fooling around, just turn the ignition back to ON, and it continues running like normal.
Don't try this one at home kids. LOL! It's probably a better idea to just put it in Neutral instead of turning it off.
I am not sure Mrs. L,TOWM would appreciate me experimenting with her mini-van in this manner.
Sorry, but that's just not true. It does turn off the engine, but turning off the engine means it is not turning any more.

Power steering and power brakes both depend on the engine. When the engine stops, you will have no power assist for either. Without power assist, steering is somewhat more difficult while moving, becoming more difficult as speed decreases. Braking is extremely difficult. You could stand with all your weight on the bake pedal with both feet and still not slow down very quickly.

Any time my engine has stopped with an automatic trans, whether intentionally or not, I have had to re-start (as in, turn the ignition key all the way to "start" and release, just like starting it up in the morning) the vehicle, not just turn the ignition back to "run".
