Technically every single driver who did not fully accelerate into turn 9 should have been penalized, as this is what they wrote in the report
At the end of Q2 [insert driver name] slowed down at the entry of T9 to create a gap for his final lap. This is contrary to the Race Directors event notes 24.2a.
This is event notes 24.2
During any practice session, any driver intending to create a gap in front of him in order to get a clear lap should not attempt to do this between the entry to Turn 9 through to the exit of Turn 10. Any driver seen to have done this will be reported to the stewards as being in breach of Article 27.4 of the Sporting Regulations.
It wasn't even just about being slow between 9 and 10 but going slowly INTO 9.
So going with that driver tracker that would have been everyone in the queue apart from Leclerc and mayyyybe Norris, so Verstappen, Sainz, Stroll, Ricciardo, Hamilton Russell, Bottas and Perez.
Vettel actually accelerated the moment it was possible by the looks of it but he was the one who impeded Alonso.
With all of them getting a +3 penalty in the order of the infringement the starting grid would have been the one on the left (assuming i have not made a mistake, actual grid on the right)
1 L. Norris M. Verstappen
2 M. Verstappen L. Norris
3 P. Gasly S. Perez
4 L. Hamilton L. Hamilton
5 S. Perez V. Bottas
6 Y. Tsunoda P. Gasly
7 V. Bottas Y. Tsunoda
8 C. Leclerc G. Russell
9 F. Alonso L. Stroll
10 L. Stroll C. Sainz
11 S. Vettel S. Vettel
12 G. Russell C. Leclerc
13 C. Sainz D. Ricciardo
14 D. Ricciardo F. Alonso
15 A. Giovinazzi A. Giovinazzi
16 K. Räikkönen K. Räikkönen
17 E. Ocon E. Ocon
18 N. Latifi N. Latifi
19 M. Schumacher M. Schumacher
20 N. Masepin N. Masepin
It would have moved Alonso up the grid and shuffled some drivers around.
