Many newer cars have engines that can over power the brakes. Don't pump the brakes. Don't turn off the ignition. Hit the brakes and shift to neutral. Sounds easy but is it? Practice it first in a safe area according to Consumer Reports I understand that the Toyota's involved in the big recall use drive by wire accelerator control. There is no longer a direct mechanical linkage to the engine. I have had a gut feeling for some time that there may be more than just a carpet problem.
