Sports Mole rounds up all of the latest news regarding Formula 1 on Tuesday, September 22.

Tuesday morning's Formula 1 news roundup:

F1 tipped to stop Hamilton podium activism

F1 will have clamped down on drivers making overtly political statements on the podium, according to former driver Vitaly Petrov.

The Russian was referring to Mugello, where Lewis Hamilton wore a t-shirt calling on American police accused of shooting a woman during a raid to be arrested.

Six-time world champion Hamilton has been wearing a 'Black Lives Matter' t-shirt on the grid all season to date, but that may be interpreted as a statement rather than an endorsement of the controversial political movement.

Mugello was the first time he took an overtly political statement onto the podium and post-race interviews.

"For me, this t-shirt, on top of calling for everyone to kneel, was too much," Petrov told Championat.

"It is a personal matter for every adult. You have the right to speak out on social media or give interviews, but I think the US government is well aware of these problems already.

"But to call on that in Formula 1 itself ... I think half of the spectators didn't even know what the shirt was about until it was explained to them," he added.

"And let's say a driver admits to being gay - will they come out with a rainbow flag and urge everyone to become gay as well? I think the FIA will no longer allow such behaviours," said Petrov.

Petrov also said Russians - including Daniil Kvyat - do not kneel for any reason except "before God and to propose to your future wife".

"In Russia we have a different mentality, and we do not have the problems that Hamilton is talking about. There should be respect for everyone," he said.

Aston Martin 'will suit Vettel better' - Schumacher

Sebastian Vettel will return to "his old strength" after leaving Ferrari at the end of the year.

That is the view of former F1 driver Ralf Schumacher, who admits the quadruple world champion does not look strong alongside Charles Leclerc in 2020.

"That's the way it is in Formula 1," he told Sky Deutschland. "If everything doesn't fit together, gaps like that are possible."

Schumacher says it is clear that the Ferrari-Vettel combination "no longer works".

"All improvements and further developments at Ferrari are tailored to Leclerc's strengths and weaknesses. He is their man of the future," he said.

"That's the big problem for Sebastian: he needs a different car than Leclerc. Anything that helps Charles doesn't help Sebastian. This explains the big half-second time gap in qualifying."

However, Schumacher is expecting 33-year-old Vettel to fare better next year after switching to Aston Martin.

"I am firmly convinced that we will see Sebastian back to his old strength at Racing Point," he said.

"There are many reasons for this. First, the car will suit him much better. In terms of performance, it is generally faster than the Ferrari, but also easier to drive. The balance will clearly suit Sebastian better."

Schumacher also thinks Vettel will enjoy the atmosphere at Aston Martin much more.

"They really wanted him," he said, "which is a good feeling, especially in his situation.

"They are putting great financial resources in, so it will be a small, compact team with all the potential and the support of Mercedes.

"Also, he will have that 'feel good' factor that is so important to him - comparable to Red Bull in the past."
