I agree HTower, they already put their lives in danger in that pit stall when cars are coming in and out. When cars are racing, like they were in those last couple of laps, there is no reason to be standing in the pit stall watching the race. That is just asking for trouble and they got what they had coming....sorry to say, but stupid is as stupid does.
I mean look at what happens to fans in the stands when debris comes flying and they have the catch fence there, we have already proven that does not always work...then there was the FOX Sports Camera in the Charlotte incident that damaged cars and debris from the camera cable and cars injured fans. These guys have nothing, but what is a wall about knee high.
They should be staying behind that wall unless their driver is coming in, it is a red flag, the beginning of the race before the green flag, or after the race and teams have come down pit road.
