VX_PA - I haven't been "surprised" by my VX yet, but I can make the tail break loose real easy on snow - start from a standstill as if you are at a 4-way stop intersection, turn right and accelerate while turning. I do it all the time - TOD kicks in and pulls me through the turn while the tail swings around on its own. I usually end up making a 100-110 degree turn rather than just 90 degrees and have to steer back left once the tail-end has traction again.

I'm pretty confident that if I really goosed it instead of just tapping on the accelerator, then I'd be seeing at least 180 degrees instead of just 110. But I haven't had the opportunity to try it safely yet.

This is all with the stock tires.
