I thought the problem with braking to overcome a runaway engine was that people don’t commit to it. If you brake hard to a stop then it will work, just like you say. But if you brake some and try to figure out what’s wrong and brake some more and let up and fiddle with the accelerator and brake a bit more and on and off like that, you’ll overheat them to the point that they won’t be able to overcome the engine anymore.
