to make an accelerator on a motor vehicle achieve its peak for reaching maximum speed and not be able to shut it off once the vehicle is in motion and has achieved a desired point of pressure, so the pedal continues speeding up the vehicle without the driver exerting any physical pressure,
have seen this on a go cart, where the driver was unable to stop the cart until it ran dry of fuel, fortunately it was on a wide open track and maximum speed was still manageable despite the drivers obvious panic and fear at no longer being in control of the cart. the cart sped up and held maximum speed independent of the drivers actions once the accelerator was pressed to a certain point,
