Well, tbh, the people doing laps are usually friendly folk.
When I turned up for the first time, I spotted an S2K with UK plates on and he had just came in from a lap, so I went over and asked how then track conditions were.
He replied it was a little damp in places and then also asked what I was driving, to which I replied the Zed.
He just told me to take it easy.
Also helps if you speak german and then be a bit social with other owners that are hitting the track.
Everybody there is there for the same thing and the main thing is to have a good time.
Of course Dan, you will get progressively faster as you get used to the track, just don't go there and expect to be doing fast laps by the end of your first day there.
