What ever happened to the old saying about the first person you want to beat is the guy in equal machinery (aka: your teammate)?Vettel was a world class dick in this race, but I don't know why Webber would expect anything less than this from his teammate. The way I see it, Vettel is probably moving to Ferrari next year, so Webber has 2 choices. Be a team player and retain his seat for next yr, or secure another drive for next yr, then crashing out trying to kick Vettel's ass all season long.
What Vettel did this weekend was reduce his chances of winning a 4th title this yr, don't expect Webber to help him out with traffic to maximize points comes seasons end if the championship comes down to the wire.
Also, I don't remember Webber ever helping Vettel in his 'chips. He's a good driver but he really is a number 2 at redbull. Not because he can't win or doesn't get the same upgrades, but because he can't go toe to toe against Vettel for a complete season. A few races here and there but not a constant threat.
