Most of you are missing the point here.

It seems that most trackday cover only covers damage to your own car. So if you crash into someone, you'd still be screwed unless you had 3rd party cover on top.

No doubt a lot comes down to the criminals using so much small print and not detailing what you are covered for in well explained policies, that you pay your money and really dont have a clue what you are covered for in the first place.

What the guy who is getting sued needs to do now, is counter sue either the organisers of the event, or anyone else he deemed caused the crash....and it becomes a never ending situation.
