Unfortunately I can't make it on the 15th.
I've already suffered the Goodwood solo track experience and by the third session on my own was getting bored.
Bob17 is facing a similar problem for the BHM Goodwood day on the 6th June.
It is a ridiculous situation which as R1NGA says is spreading around the tracks. I'm sure other types of car have had far worse accidents and you don't see them being segregated.
Also, from what the chief instructor was saying about one of the Goodwood incidents I don't believe it was even a M3W as he was adamant it had "the larger rear wheel".
Anyway, good luck Phil and I hope someone comes to play with you.
