Just a little background for the newcomers, on what happy laps ARE and what is acceptable behaviour
No helmets are required, because the idea is there is no real DANGER of personal injury on track
Speed around track is around 110KPH, 160KPH is acceptable on the STRAIGHT (this is what we were told last time, whatever the marshal says on the day goes)
Overtaking is to be either on the straight in a sensible manner or when the person infront waves you past them at a suitable time (no indicators are to be used, and they are to be ignored to avoid confusion)
No excessive traction loss i.e drifting, tailgating, dangerous manouvers or overtaking will be acceptable.
Stick to these rules and you will have an awesome time, if not then you may have infectious rangas set upon you (sorry colin)
