We are going next summer. You have to be 18 to drive and my son doesn't turn 18 until next June. I just want to go to the Hertz counter at the airport in Frankfort, rent a Golf (or similar) and go drive it like I stole it. It's only 30 Euros (or less if you buy in bulk) for a lap.
Sounds like a bad idea.
I had no idea that non-professionals could drive on the track.
Just recently, a new lap record was set at Nürburgring - one car, no one else on the track.
Have you seen the You Tube video?
The driver beat the old record by more than a minute!
