"Rev protector"?

Hope you don't mind, what exactly is going on with the various "throttle sticking" runaways anyways?

I wouldn't mind doing this maneuver with my students, however when I have them push to neutral after making a turn when I turn off the vehicle, I stress to NOT push the gas pedal before restarting AFTER putting it in neutral, about a third of them forget and push on gas in neutral anyway. It would be even harder to remember to let off the gas for a fraction of a second.

My boss wouldn't want me or my students pushing to neutral from a high speed (unless she was sure it wouldn't hurt the engine or transmission)

Another concern here is the ability of your students to use the shifter properly. They should practice shifting from Drive to Neutral without moving the lever too far and getting Reverse.

If a car throttle is stuck down, an inexperienced driver might get too anxious and move the lever too far, and engage Reverse. On lower-powered cars, the engine would probably stall. On higher-powered and RWD cars, you might just get the drive wheels spinning backwards while you are moving forwards, leading to a loss of control.
And such a move is always very hard on the transmission.

Virtually all automatic transmissions have some kind of interlock device, where you can shift from drive to neutral, but no further, unless you push a button or move the lever in a particular way.
So, have your students practice the shift from Drive to Neutral in the car, with the engine off first.

Yes I have them practice that before emergency maneuvers, and as you said, every car I have taught students in has a device preventing going from neutral to reverse, but allowing you to push it from drive to neutral.

Toyota Corollas, Camrys and a few others have reports of this happening.
I just went to Toyota today and had them do what they needed to do to fix
my Corolla at no cast to me. (actually my boss since it's her car)
