I was there, but I'd left before the incident with the McLaren. He deserves the stick TBH, apart from the personal abuse about his size which is out of order and there's just no need for it.
It was a very busy day and the majority of people were perfectly fine, but there was a huge spread of cars and abilities. The marshaling wasn't up to much IMO. Plenty of people getting repeatedly black flagged but not chucked out and later in the day it became a bit of a free-for-all probably because people realised nothing was going to happen. Given the publicity this has generated I imagine there is a huge amount of s**t flying around at MSV.
As to why didn't anybody have a word he was one of about eight guys constantly together in a group, I personally didn't have a problem with him as we didn't head out on track at the same time very often but if I had have done I wouldn't have fancied going over and saying "Excuse me mate, but I don't think your driving is up to scratch" in front of his mates.
