I don't think the electronics saved me exactly but they sure did a lot of something or other when I hit some black ice 2 days ago in a lane, I had no idea it was there, couldn't see it at all, driving normally and all of a sudden I have little to no control and the car is sliding towards the hedge mid bend, I reacted quite fast in anycase despite being very surprised as I didn't think there was any ice about that night. Really it was a case of keeping the power in check faster than I could do it myself and helping to regain some traction and retard a spin
Managed to avoid the hedge anyway, I think it was the car working with me more than the electronics alone that kept me on the road. As is always the case really, they help you, not so much fix your mess.
There is a water leak across that road though I now find out, and it had frozen as a sheet of black ice, but because elsewhere it wasn't wet, there was no other ice about and of course I wasn’t expecting it, I just got caught out there really. I wasn't driving fast at all, perfectly normally if not slightly sedatley if anything (I usually do drive like that now, the car just keeps me in wafting mode more than racing)
I’ve had my backend trying to break lose (and actually breaking lose a couple of times in the snow) several times of late in the cold weather. On a wet, greasy and icy road the big old armchair on wheels is surprisingly tail-happy.
