TC is definitely going off all the time, it's simply intrusive and I can't figure out anything good it does. Hit a slick patch on one side of the car and instantly I get cripple mode for several seconds, even though the other wheel bit in fine and the whole patch was only a few feet long. Similarly, trying to accelerate while turning off a side street on wet roads (not even icy) one wheel would slip a little and boom there goes any hope of getting out and going before the oncoming traffic reaches me.
ABS sucks when you might really need it, and kicks in far too easily. I'm actually afraid it might cause an accident and not at all convinced it will prevent one. It seems broken to me, though, I've driven many ABS equipped cars, and A) it isn't easy to get it to kick in and B) when it does, it feels more like driving over rumble strips, not like this where your car stops responding and starts pounding you in the face.
