I'd still need to see some citations. Brakes "totally burned through" takes a *long* time or *really* crappy brakes, you certainly aren't going to burn through a perfectly good set of brakes on one drive. If your throttle opens up and you brake to bring yourself to a *stop* your car will stop. Brake fade could have certainly occurred, it only requires the brakes to get extremely hot, which generally means long periods of brake use. Coming to a stop from highway speed isn't a long enough period, otherwise you'd have a ton more accidents at the bottom of long hills due to fade.
Now, the acceleration issue could still be the cause if the drivers used the brakes to keep the speed in check for a while instead of bringing the vehicle to a stop. I won't claim that the accelerator faults aren't part of the problem, but proper driver education and response to the sudden acceleration would have prevented many accidents.
