The experiences are somewhat different - Like, in my case the worst part about the SC was ppl's lack of driving safely behind SC and when we get a green flag.
But, It also concerned me that we got a full course yellow, but no SC were to be seen anywhere. It cased confusion, and confusion + racing doesn't mix well - I carried on in confusion for more than a lap before I started to push again.
Also, I would say that the SC driver need to slow down 15-30 sec before race goes green, so the field can get a chance to get gather up.
When I was behind SC, I saw this - It was on the edge to become bad, but think about how it was for the drivers even further behind.
SC can work, but it need some work and especially ppl need to think about what they are doing while being behind one - and that includes not staying behind SC as the first car, if you aren't the leader... that hurt us bigtime :|
