It doesn’t necessarily mean that the media is morbid. Not everyone was watching and there will be some that will want to see the crash. Fans and drivers in other motor sports. That can’t be helped. They spoke of the catch fence causing a lot of damage. The video will probably be watched by some to see how to improve that.
I understand your point where some people haven’t seen it but then again, when I’m home and watch sports it seems that any accident is shown over and over and over again.
