Yes Webber wants to win the championship!! dduuhhh!!!
He wanted to make sure Vettel had a tough time getting past. NMothing wrong with that. He forced Vettel into making a childish move, no actually, that's offensive to children because I've seen Cadet karters handle that kind of situation better. Webber has extended his lead and Vette is rattled... so I guess for Webber it's worked out perfectly
Vettel has learned his lesson anyway, I don't think he'll be making the same assumption again.
