I'm not saying you are wrong but I can see where this is less effective as a quick response. You have two forces at work - the engine driving the car forward and the brakes trying to stop it. Neutral eliminates the forward motion immediately.
Now that might raise hell with the engine RPM's but if I saw the tach red lining my immediate reaction would be to turn off the ignition key.
Good old Newton already had figured it out: F=m(x)a.
Look at your car's performance 0-60 mph vs. 60-0 mph. The latter figure should be the much shorter time. I.e. brake power trumps engine power. (Decent brakes = 1000+ hp of decelleration). That said, removing the forward force of the engine by going into neutral in an emergency is a good idea. And the rev limiter will likely save the engine from going BOOM anyway, even if it sounds scary.
We’re both right.
I looked up an article in Car and Driver, that explains things better than I could. They actually have real-world data, which always helps (although, made-up data is used in more arguments).
