As a side note, there are plenty of ESP/TC equipped vehicles without
drive by wire. BMW used to use (on all models) a second throttle body
ahead of the one connected to the go pedal that was natually open and
closed by the TC system. Other TC methods reduce ignition timing
advance, cut fuel on random individual cylinders, and (if equipped)
reduce boost.
