I think you misread the conversation you jumped into then. Rollo said that "You should be at a distance that you're able to pull up in time no matter what the car in front does," I disagreed that this was a standard in any form of racing, and you said I was wrong.
Vettel wasn't trying to overtake Hamilton when he ran into the back of the Mercedes, so rules on overtaking aren't really relevant.
Um, I think that when you run into somebody from the rear, you have overtaken them.
I think we saw this one coming, didn't we? Like it was for McLaren in their boardroom battle in 2009 onwards, that decimated the potential of the team, and the consequential departure of key staff....
Wet conditions.
Portuguese Autosport brought something to the table... the WRC2 crews are using a WRC spec tyre that is harder than the spec Meeke and other CPR runners are using.
