A bit of confusion between (a) and (b) below. At Brands last week many of us where oversteering over the kerb exiting Graham Hill Bend. It was good fun.
"14.5. Drivers must use the track at all times. For the avoidance of doubt:
(a) the white lines defining the track edges are considered to be part of the track but the kerbs are not, and;
(b)
a driver will be judged to have left the track if no part of the car remains in contact with the track.
(c) Should a car leave the track for any reason and without prejudice to (d) below, the driver may rejoin. However, this may only be done when it is safe to do so and without gaining any advantage.
(d) Repetition of serious mistakes or the appearance of a lack of control over the car (such as leaving the track) will be reported to the Clerk of Course and may entail the imposition of penalties up to and including the exclusion of any driver concerned."
