That'll slow the car down, and bring it to a stop if the brakes are in good condition.

It's really simple to recover from a jammed open throttle (it's happened to me) - and I think it's the kind of thing that ought to be taught in driving lessons.

You have heaps of options, either knock the car into neutral, turn off the ignition (before the steering lock), stand on the clutch (if it's manual), stand on the brakes or as a very last option gently start to apply the parking brake.

Forgive my ignorance, but is a "state trooper" a cop? I can't believe an off duty cop would let the car get up to almost 120mph. Aren't they trained?
