No, I haven't done it in a parking lot. Usually I can do it on an off or on ramp, usually I have been in 3rd gear, 4-5k rpm. Make sure you have some experience at that speed in a turn - I usually scare my passenger
I can make it last through a turn, about 5 seconds, but then the off/on ramp straightens out and then it decelerates like normal.
Honestly, when it first happens, it will scare the crap out of you, if you are entering the turn at high speeds (which is the requirement). I usually enter the turns at high speed, lift to scrub some speed off, and hope to accelerate out, but with the stability control on and when I take my foot off the pedal, it continues to drive - real freaky and uncomfortable. But, now I just turn off the stab. control.
