You don't have to pull the key out, just move the cylinder to the position where the key will come out an some cars lock the steering even with the key still in.

Ps.. I just noticed you do have to shift to park to get the key to turn to that position. Some really new cars won't actually shift into park or reverse even if the shifter is moved there while in motion with electronic controls. So maybe you can shift into park while in motion and it will stay in neutral but then the steering lock becomes effective. It does seem hard to do.

A kill and restart ability while in gear with no shifter or key activity (like the factory auto stop-start systems) would be the best but I bet we would also get more roll away or drive away accidents as well.

On an old manual transmission car, you could put the car in gear and use the starter motor and regular battery to move the car a short distance like out of an intersection. No interlocks and saftey nannies. It's probably just a matter of time until these auto stop-start systems get old and glitchy causing all kind of 'Maximum Overdrive' "accidents". The nannies in the systems is what the aliens will use to conquer us. I should write a script, add Zombies, base it in Alaska, the next Discovery channel hit.
