Should Vettel be banned?

[Bagwan]

Both drivers are guilty in this "incident", but someone had to start it.

Lewis did play his role , Mia , but Seb was right to say it was his own fault .
Lewis didn't react to Seb being closer on the second restart , but it was not his role to do so .

I'd guess Vettel expected him to do so , and thus , was caught out .
A silly error , and an improper assumption led to a dumb move .
