This is opening up a can of worms. I've ridden three times with Team Hammer at Daytona, twice in the school. When I first heard of the accident, I'm sorry to say I was NOT surprised. Frankly, the "school" is not much of one. Very unstructured, not very instructive and as Charlie says, very suspect to be running three skill levels together in the same session.
I was supposed to be there last October, but had a last minute work conflict. Several friends went and it was their first time to Daytona, which again as Charlie said is an intimidating track and certainly questionable as a first-time track experience. A friend of mine actually has GoPro footage of the accident from his rear-facing camera, and it is sickening to watch. Even more so because IMHO it was completely avoidable.
That Canadian racer who crashed into instructor Rick Shaw was utterly inappropriate in his desire to cut "fast laps" so he could learn the track before his CCS races later in the weekend. He was drafting another "fast guy" and they were clearly unsafe in the speed they were attempting to cut through the school traffic in the 2nd session of the day. Team Hammer has enough control riders that someone should have been either leading this "fast guy" group safely through traffic (i.e. slowing down where the accident occurred as from my friend's video it is plain to see that the track was almost obscured with relatively slow traffic coming off of NASCAR 2, which as a rider you can see all the way through), or a control rider should have quickly gotten in front of them and slowed them the hell down and given them a serious talking to in the hot pit.
In the previous 3 times I had ridden with them, I saw multiple close calls, and again, was not surprised to see what happened but was quite saddened that it did. I understand if danamite14 was freaked out, my friends that were there that day were as well. However, as Charlie and others have said, it is not indicative of how well-run track days are conducted. Jennings GP is very well run at all of the events I have been to (10+ of them) and would be a great place to try again if you feel up to it.
I love Daytona and don't race anymore so doing Team Hammer is the only way I could get on the track again. However, if I do go back (if they even do it ever again) I'll only be going back for the track day sessions and not the school.
