It was a great race yesterday.It would have been even greater if Bottas would not have slowed down that much in the first safety car restart of the race which brought a big crash
What Bottas did at the restart was way to dangerous for the back of the field.
I don't think Bottas did something wrong, he didn't break any rules. He started so slow in order not to give Hamilton slipstream
It did initially look like it was Bottas' fault - even if it was within the rules and perfectly acceptable strategy... however, after the race both Hamilton and Albon (as well as Bottas) said the fault lay with the safety car not letting the drivers start racing until the very last minute. Apparently this has been a trend recently, although I was not aware of it until I read the article:
Hamilton said the way governing body the FIA handled a safety car restart, which led to a multi-car pile-up that took four cars out of the race, "put people at risk so maybe they need to rethink that".
The top three drivers all expressed the same opinion about the FIA's decision to delay the point at which the safety-car lights are extinguished, which defines the moment from which the leader can control the pace.
Hamilton, team-mate Valtteri Bottas and Red Bull's Alexander Albon all said the decision to do so at the last corner left the leader with no option but to back up the field until he reached the start-finish line, where racing can start, to reduce the risk of being passed.
At Mugello, this led to confusion among the drivers behind.
Haas driver Kevin Magnussen slowed down as he approached the line, reacting to cars in front. Williams' Nicholas Latifi took avoiding action and, unsighted until the last second, Alfa Romeo's Antonio Giovinazzi rammed into the back of Magnussen's car. McLaren's Carlos Sainz then hit both Latifi and Giovinazzi, who came close to rolling, before his car settled back on to the track.
Hamilton said: "It's absolutely not Valtteri's fault at all. It's the decision makers. I don't know who.
"They have been been moving the switching off the safety car lights later and later. We are out there fighting for position. Especially when you earn a position like Valtteri earned the position of being in the lead.
"Obviously they are trying to make it more exciting - but today was a little bit over the limit perhaps. But he [Bottas] did exactly what anyone would do."
