In the old days of a cable linkage between the accelerator pedal and the carburetor, my brother had the experience of the return spring breaking. He turned off the ignition and the car stopped. Another option is to put the gear selector in Neutral. If you are truly concerned that the car won't stop, I don't think you will be worried that the engine will overspeed and throw a connecting rod. But then that would stop the engine. I do agree with having an interlock between the brake pedal and the electronic throttle control, but technology can't replace good driving skills.
