GM ignition switch debacle, let me be insensitive for a min

the vacuum does stay in the booster for a little while, but how long and how much assist that gives you i have no idea.

It's typically one or two presses of the pedal, but then yes, if you wasted those panicing, now it's pretty hard.

also, my question is, does the engine still spin while wheels rolling and if so is it still generating vacuum ?

Good question. It sounds like in an auto it does not, or I guess this wouldn't be as much of a problem. Will try on my next rental car.

From what I've heard, at least with some of the cars, the steering is locking.

Hey, if that's the case, it would explain a whole lot. But it sounds pretty clear that it's just moving from the spring loaded ON position to ACC, which wouldn't lock steering.
