Vettel is in the lead, he has a right to close a gap, Raikkonen is the only one going straight and at this point he is ahead of Verstappen. Everyone is responsible for their own car and if you have to let off and let someone passed to avoid a crash then that is what you do. Verstappen didn't. You could just say it was down to unfortunate sequence of events. But if anyone is to blame, it's your boy Verstappen. Who has form.
Vettel was in the lead, why would he go right? Verstappen was being overtaken by Raikonen, he could and should have let off. The result of him doing that is losing second position and continuing to fight, the result of what he did instead is the front 3 which includes himself are out.
