Massa hit the corner by 1.5m before the apex, whether this was to cover Lewis or attack Webber only Massa knows.
That's a defensive line all the way. He was trying to block the inside, its pretty common... they turn in earlier... force the guy to pass on the outside. If he had been trying to move on Webber, he would (or should) have been carrying more speed into the corner... or actually diving into Webber.
BTW you're seriously comparing a botched passing attempt on the tightest turn in the sport, to the botched Vettel/Webber pass in Turkey last year? 
But that's exactly my point... Monaco was a much more unlikely move, and yet everyone blamed Vettel for 'expecting' Webber to give room. Wasn't Vettel "racing"?? The same racing we all got robbed with the save fuel message. [i'm being sarcastic, because i think Mclaren were right to calm things down and avoid contact]
Regardless of your POV... remember my point yesterday about POV dictating how you'd feel about a situation? 
ok ok, i'll go read that post

Pssst.... Canada is in a couple of days.
Sheesh ... someone said it.!!!!
Canada is yet another unpredictable race. I doubt it'll trump Monaco, but we're likely to have our post-trigger finger busy for a while , because for sure... something weird/borderline is going to happen

Came out fighting indeed.
