By the way the Nurburgring is no longer a "public toll road". It is now a private track. This is why they are able to link the GP circuit and the Northloop on certain days now. This changed last year.
As such you are absolutely definitely not covered, and certain insurers have been known to go a step further and void your policy completely if they've found out you have been on track.
