A couple of items
1) from a comment from Leclerc and Stroll incident
When asked about the incident, Leclerc said it was the result of dirty air from Stroll’s team-mate Sergio Perez, who was running right ahead of the pair in sixth place.
“I tried to go inside Lance at Turn 4 and then in the middle of the corner Perez took the apex and when I was behind him I understeered quite a bit and then we made contact with Lance,” Leclerc said.

2) Hamilton's, practice start, I cannot fine a video/Picture of it again, but I believe when you look at in detail, you will notice like it was done before. There are black tire marks there, that suggest either a F2 or F1 car had done it before Hamilton...
just notes and observations
