Ah, I misunderstood you.
More like 250m, I reckon, having looked again at the video. It's really hard braking and really early too. Petukhov might have reacted more quickly for sure, so a little blame is on him, and indeed the guy encroaching on Phowley didn't help, but such an extreme decision means that Phowley has the lion's share of the blame, for me.
You can't be serious, I guess. This is a racetrack...
Well, I know that this is a racetrack.
But the guy in the front is not suppose to adapt his braking point to the guy behind.
He can choose his braking line too, even if a little surprising.
It may be surprising for the guy behind. , but after all he may have a problem on his car, ….
For sure, it is risky to brake a lot to soon. You can be hurt in the back, and it is what happened.
But we don't discuss about how risky it is to brake earlier. We discuss about who is responsible or not.
My opinion remains, that the guy behind have to be careful in any situation.
Of course I may be wrong. I personally try not to surprise the guy behind me.
I must say that in my case, I am more "victim" of divebombing by braking at normal distance, as "victim" of collision after braking too soon.
(But It seems that for some guys, normal guys are always Breaking too soon. They expect us to brake a lot too late, in order to leave the track and make them the path free !!)
Maybe there is somewhere a reglement which make braking at "normal" braking point compulsery, but I don't remember having read such thing anywhere. Gentlemen agreement for sure, but in case of collision, I think the guy behind should be guilty
