Mmmm, I got my insurance through Adrian Flux, the insurer is Red Star Equity and in the policy doc. all it says is "The following uses are not covered. â– Racing, pacemaking or being in any contest or speed trial or any rigorous reliability testing on your vehicle (apart from road safety rallies and treasure hunts). â– Using your vehicle on any race track or circuit, other than accidents to which the Road Traffic Act applies." Which to me doesn't exclude the 'Ring as the German road traffic law applies.
