Not if you ease it on. Its other name is "emergency brake".
Try it sometime. See exactly how long it takes to stop the car. Be sure to report back on how well your "emergency brake" works.
Seriously. Do it.
I don't understand why people don't try stuff like this when they're out on a quiet road with nobody else around. Stomp on the brakes. Yank the controls. Try stopping with just the engine, etc. It builds confidence and might save your life one day. If the last time you did an emergency stop was on your driving test then you're doing it wrong.
