BTW, I rear bumped some guy on a GT-R, as I was trying to slipstream him down the rear straight. He braked "miles" before the braking point, I was full throttle, couldn't avoid it. I was going to brake earlier than normal, as I usually do when I'm on the back of other car, but not the breaking point to very early braking. With the new system could see he got a 10 sec penalty, which was unfair to, as I believe it was his fault, there was no real harm to me, he was the one sent to the barrier and even brake testing me, I've to be ready to take avoiding measures. A pure racing incident.
