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.

Thanks Cody, I stand corrected, as I forgot these early TC systems. My
mistake.
