Everybody: Permanently engrave this on your consciousness.
The brakes are more powerful than the engine.
This is true for every car that exists. The only exception is a car whose brakes need to be repaired.
If the engine runs away while you are stopped or barely moving, put both feet on the brake pedal and shove like hell. (If the pedal is too narrow for both feet, put one on top of the other.) One of three things will happen:
(1) If you have an automatic, the car will come to a stop and engine RPM will rise to what is called the stall speed of the torque converter. (This technique can be used at the drag strip to get a good start. When the lights turn green, keep your foot all the way down on the accelerator pedal and release the brake.)
(2) If you have a manual with a strong clutch, the car will come to a stop and the engine will stall.
(3) If you have a manual with a weak clutch, the car will come to a stop but the engine will keep running and the clutch will burn up.
Things get messier if you are on the highway at highway speeds. Although the brakes are more powerful than the engine, stopping distances will be very long because the braking force is substantially offset by the engine torque. Brake fade may also be an issue.
If I hear someone say that they braked as hard as possible but the car wouldn't stop, I reply, "Bullsh!t. You just didn't shove very hard." If you can do a deep knee bend, you can shove as hard on the brake pedal as your body weight and probably harder. Most adults weigh at least one hundred pounds. That's more than enough to lock up the wheels on any car.
Thirty years ago, I raced SCCA Showroom Stock. I also used the same car in Solo II which is the SCCA's name for autocrosses. Racing substantially improved my Solo II times because I finally learned, on the track, how to brake hard. On the Solo II course, I became able go to way deep into corners and brake very hard rather than coast into them with only a token brake application.
