Good for Massa at Ferrari and for Vettel.
Not sure how good this deal is for RBR actually, when Adrian Newey makes another lemon (which in probability he is due to soon) I doubt Vettel will feature very much, unlike the likes of Lewis, Alonso, Rosberg.
This is based on Vettel barely beating Webber (I don't actually believe he is that great - I would consider him average at best) in a super dominant car last year. I think Teflonso is set to have some fun and a few WDC in the years to come!
