As for what the cruise control uses to operate, our cars are drive-by-wire and assuming everything else (which is probably the case) is electrically controlled, then the cruise control modifies throttle input electronically.
I'm not a mechanic, but would have to agree on the theory of the drive by wire method of controling the cruise. It does say in the manual about up/down shifting with the cruise engaged, but shifting must take place under 4 sec. Supprised me the first time it stayed on after shifting, then looked it up in the book.
Thanks for all the inputs, still waiting for my "morning call".
