I had a Ford F150, ~2005, with a failed throttle pedal sensor. Ford were clever enough to give the car a high idle limp home mode, where the computer opens the throttle just wide enough to allow the truck to putter along at 30mph, but not open so far that you can't easily outbrake the engine in D. You can't do that with a cable. But then, cables don't break nearly as often as throttle pedal position sensors do.
