As Rosberg quite rightly highlighted, Verstappen was trying to let Hamilton know he was there and knew the left side of the track coming up would not help Lewis in the tow.
Especially so, as there was no DRS for two laps anyhow.
Absolutely crooked. The guys who drive these rockets are mental gymnasts, they process information at speeds mere mortals cannot comprehend.
Same as last week on the brake check, Verstappen is doing it right at the moment he knew the line was coming up for DRS.
Nobody should underestimate the multiple processing and calculating which is done by people who drive 180mph into a blind corner in the wet.
