DF Trackdays
Driving Fun trackdays are characterised by a tight organisation, but an agreeable atmosphere, both in the pitlane and on the track. They are emphatically not racedays and things like overtaking in the braking zone and doorhandle to doorhandle dogfights are strictly prohibited. The idea is that everybody should feel at home on these days, from the fast, experienced racer to the absolute beginner in his streetcar and this is only possible if everyone shows some consideration for each other.
The faster driver should use his experience to show consideration for the slower drivers and the slower drivers are expected to be aware of possible differences in speed and to keep a close watch in their mirrors.
