Watching that video, if not told I would not have realized it was 3 wide. It looked like you cleared that RSX and had the run on it, but with only front facing camera it is hard to tell. With the middle car in that 3 wide it is extremely tough to gauge the apex of that turn.
Before I say anything else, I had 2 incidents this year at Thompson at turn 1 which is right off the main straight with a combo turn 1 and 2. The first incident was with a CLK, which the driver had misjudged his turn in point along with braking point. Similar to this video. The CLK put both of its leftside tires (hard right turn) off of the track and immediately tried to regain traction after turn 1. I am sure the driver of the CLK was Sawing off some sort of Tree trunk from his steering column while playing Chopsticks with Tom Hanks in the movie 'Big' with the clutch, brake and Fun pedal. He nearly ended the race for me by almost T-Boning me in somewhat of a similar fashion, but not quite. I lucked out and so did he with no contact. Reviewing the video though, and a little more experience the driver should have doubled down on the brake and clutch and rode it off for a penalty. Which leads into...
A little later I had a run into turn 1 myself, I hit the brake point exactly where I wanted it, but slipped the front right wheel for a fraction of a second leading to a slight front right lock up. I had just passed a VW Beetle which would have been on proper line to make the first turn right behind me. I had so little time to save from the lock up and tried before Mr. Medulla BadIdea got hit over my head with Mr. Bringiemycar in one piece home. Realizing I could have been your car in the video (although at the time i did not know that) with my drive tire going off just to fight to regain control if an even if I could, I decided to dump my clutch and brake down releasing steering into the grass.
In the heat of the moment, it looked to me like your driver did a reaction to the situation. He had all of but a thousandth of a second to make his mind up and do what needed to be done. Thank goodness no one was injured. Although this turns into many things, driver confidence loss, financial lost for 2 cars, 2 teams that had a race both were looking to finish, 2 teams that worked very hard to race and prove they could finish the race. It was over in a mere second.
I feel it is videos like this one that need to be shown to every racer during the driver meeting an especially for the rookie driving meeting. I wish I had the video editing ability to do this but I lack the ability and equipment to do such. If anyone would like to do this I can send in my 2 moments which maybe can help out with a "emergency safety" video of what to do and not do.
I hope your car gets fixed and you guys get back out on track again as soon as possible. It sucks that from moment of impact until you found out your driver was ok had to happen. None of us want to have this happen to us, we must take it upon ourselves to educate and elevate each other to not only increase our awareness of the x factor of possibilities on track. We need to help each other out on refining and building upon our own racecraft. Sorry to rant on this. The safety equipment did its job and everyone was ok.
