my thoughts ( i wasnt able to attend this one!

)
Too busy - we had approaching 60 cars booked on (not crazy for 4hr session) BUT i think the main issue was additional drivers! That meant certain cars were on track alot!!! We should have been charging £10 per additional driver but this was lost somewhere and didnt happen. Maybe we need to limit this in the future.
Some novices - yup... as mentioned there were a couple of 1st timers doing things first timers do. Staying in to the right too close to corners, too slow on the apexs etc. Everyone has to start somewhere.
A couple of incidents of dangerous driving by a group of minis. 3 or 4 minis were booked on through GrandPrix Adventures and caused some issues regarding driving too closely and undertaking into corners. They were all flagged in and given a warning. We'll ask KH marshals to pay A LOT more attention to race cars in the future. We understand they corner quicker than the average road going track car but they are also slower on the straights.... BUT they need to keep it within the rules or simply not get on! There were other mini cup cars there that behaved well so its a shame to generalise.
The crash - From what I can gather the guy in the Meastro lost it underbraking and went off to the right at the top of duffus. I must stress this guy has done a few events with us before... he isnt crazy, the car was a clean old Meastro, caged etc. This wasnt a scene from a hot hatch event
As David as mentioned - we have regulars with a wide variety of machinery. I dont want to impose limits on cars as having money is no gaurantee of common sense and decency.
