funny for sure - I took my new Grand Sport (not Z06) to the track a month ago and didn't know how to get the traction control (TC) and active handling (AH) shut off completely. There were a few Vettes out there including a ZR1, and 3 Z06s. I asked around and everyone assured me that Competition Mode is what you use, you NEVER turn it off. Car is a nightmare with any TC/AH on... fortunately I saw Mike Pettiford out there (T1, T2 and Showroom Stock Champ all in the same year, holds track record for T1 in a track prep'd Grand Sport at this track), he told me how to get it all shut off. We sorta laughed about all the other guys who can't drive without the TC/AH on to help them.
The next time I went out, one of the Z06s gave me a point by, I passed most of the cars out there except a Formula 5000 (it was an open track day so lots of various models on the course), another Z06 guy had asked me for a ride, whom was with me while I passed the Z06 and commented "You are definitely way faster than I am" while he hung on. Amazing to me to be honest... Pettiford would make me look like a fool in my own car and I am blowing all these guys completely off the course in a bone stock Grand Sport.
Right now I have a virtual flame war going on one of the Vette Forums once I told everyone they aren't really driving the car if the car is helping drive itself.
