What's he done recently? Like Alonso, he's supposed to be a great talent, but what's his performances and championships been like recently? Has he bought glory or embarrassment to himself and his teams?
Yet he has convincingly beaten Kimi having 'performed poorly'.
Outside of Hamilton, Vestappen and Ricciardo who is better than Vettle? Oh right, no one. Everyone holds up Alonso like he is a master of F1 cars but the reality is he checked out years ago and is now well past his prime. Every other driver on the grid is objectively slower, or involved in more incidents than Vettle (Vestappen is just as bad as Vettle IMO).
The only one on the grid that is a bit of an unknown is Le Clerc, he has shown promise this year but is still a bit of an unknown quantity. We will see next year, but I can imagine when Vettle is ahead by the summer break all the haters will be like 'oh but its his first season, Vettle is rubbish blah blah'
