No turning off ESP would be a accident waiting to happen! I have worked this out though, thanks to a close friend who is an ex BTCC driver and now a TV pundit! The particular road is an A road that is prone to camber change and farm muck and it was a couple of spirited overtakes that manifested the torque steer situation. Moving from main carriage to right and back on negative camber in greasy conditions the diffs and gearing tried to compensate and resulted in a left/right steer compensation at, well lets say, higher speeds which was to say, "twitchy" and needed serious concentration!
The car in almost all situations is sublime and whilst the slightly skinny tyres (in terms of large horsepower motors) are a driving challenge, the fast bends instil a Fast and Furious Tokyo drift type of experience which is great. Obviously all of this is on a track and not the highways!!!
