I can't understand why that would happen, they were on the first row of the grid so there were no distractions in front of them.
I can only assume that the pole sitter lit up his rears just a little too much, giving the second placed guy enough time to pull alongside and therefore placing each other in their blind spots? I bet the teams post race debriefing was interesting
That's what had me confused; there were yellow flags waved as the cars approached the Adelaide Hairpin, and there were no incidents near there, just for the stalled cars and the startline incident for the front-row cars.
Perhaps there was a communication breakdown as the cars approached the Nurburgring esses, and thus, the marshalls didn't wave their yellow flags.
