there are plenty of things about karlgate here

essentially he was in his car, on a parade lap, doing 15 mph when he got hit from behind, it was caught on video, his car was written off, he bought another one, and posts endless pics of it on facebook

the similarities are that they were both "on track" and both got hit by "someone else"

but after that it's a totally different matter, hence my edit of the original post asking for confirmation that it was safe to post this

my question here is "what would you do in this situation?" "who is to blame?" "why don't you get track insurance when you go out on track?" "do you need track insruance if you aren't going on track for a track day?" etc
