The Decelerator is a Brake Override Safety System. The Decelerator protects you against "sudden unintended acceleration"" regardless of cause, such as: Human error (depressing the accelerator pedal by accident), Accelerator obstruction (bunched up floor mat, groceries, tools, toys, dislodged interior panels etc.), Mechanical/electrical failure (sticking accelerator pedal, faulty sensor(s), computer glitches, external electrical pulses, Electrical Magnetic Interference EMI).In the rare event of 'unintended acceleration', the Decelerator will immediately reduce the RPM of a high-revving engine. The operator retains full control over steering and braking as the runaway vehicle is comfortablely and safely brought back under control.Very much like the crash air bags that we enjoy and rely on to keep us safe, the Federal regulators will, in the next five years or so, mandate this inexpensive life saving feature be on every new car sold in the US .
