I was wondering whether your advice regarding the switching off of both ASR and ESP in slippery conditions applies to vehicles with AWD such as the Skoda Octavia Estate. I have found that, in slippery conditions, if you overcook it (in a safe area) then providing you turn the steering wheel in the right direction, everything slows down as the power is reduced and the brakes are applied to the necessary wheel. ESP is excellent in slippery conditions. ESP is supposed to keep you going in the direction you want to go, so I don't see the point of switching it off when it is slippery.
