Like I said, have fun but don't f*ck up.
Toll??!!
I always thought it was a track..?? I have learnt something..!!
Just to clear this up, the Nordschliefe was (and still is) a racetrack but in order to allow 'normal' revenue raising traffic on, it's then classed as a toll road. You don't have to wear crash helmets and occasionally you have to overtake coaches, vans, wagons and any other class of vehicle that has the ability to exceed, IIRC, 40kph.
