If the driver of the Focus was "Racing" on a public track day in the novice group I don't think we have to look much further with who to pin the blame on do we?

Going by the fact he was out on track with others who may well have been doing their very first track session, minding their own business, driving appropriately as instructed in the briefing before hand, overtaking in the correct areas, and following the strict rules set out to protect the inexperienced track drivers, all reports I can find and hear suggest the Focus driver was driving like a total tool, and in no way taking any consideration for the caliber of the other drivers he was out with, no doubt it was the only track time he could lay his hands on and should have been black flagged long before this incident happened.

I think some of the blame has to be with the organisers, if the reports are correct about his driving, why was he allowed to stay out there? It's the organisers jobs to ensure the safety of everyone out on track as much as they can, and it doesn't seem that was the case here.
