The Tuscan Grand Prix was red-flagged after nine laps following a scary pile up involving four cars at a Safety Car restart.
On lap eight the Safety Car came into the pits, allowing race leader Valtteri Bottas to manage the pace out in front and decide when to hit racing speed. The Finn waited until the start-finish line before accelerating, as he is allowed to under the rules.
That caused a bottleneck effect behind him and at the back of the field Antonio Giovinazzi and Nicholas Latifi appeared to hit racing speed before anyone else did. Latifi quickly came across Haas' Kevin Magnussen, who was following the pace of the cars in front, and swerved out of the way -- Giovinazzi was unable to do the same and went into the back of Magnussen's car.
