CRT, sorry man, didnt mean to say stabilitrak doesnt exist but meant to say its not a mode in it self. Stabilitrak is just gm s name for ESC, electronic stability system. It uses various sensors from car ( steering sensor, yaw sensor, wheel speeds, throttle sensor etc) to determine if you are loosing control or not. If ur car is rotating to fast and the computer reads that ur steering compensation is not enough or fast enough than it puts a counter moment on the car via brake application on certain corners. That is just one of the major features.
Also, look at that manual u posted, it states ride systems because zl1 is under it too, but it calls the competitive mode a driver mode because it doesnt do anything to ride.
Nice summary table.
