It depends on what the sudden acceleration event is.
Sudden acceleration, as I said, can be broken down into a number of factors, some of which are as simple as pedal misapplication.
What brake override software will do is ensure that if your pedal is being pressed--for example, if it's underneath the floor mat--and you then press your foot on the brake, the engine speed will return to near-idle or idle, and that will calm the over-rev situation in the cabin of the vehicle.
The purpose of the ride-and-drive demonstrations we've put on over the past few weeks was to show that even without brake override software, the brakes in a car are designed to overpower the engine. You will stop in either fashion, but the brake override system gives you the added confidence that the engine is going to return to that near-idle position, and it reduces the amount of noise inside the cockpit of the car, which we think is critical, given the sort of high stress condition--
