Definitely wasn't intentional in my opinion... they crashed on a bit of a turn at speeds of 40+mph and Cavendish should really have moved up his left (like Kittel was it?) rather than his right. I think it looks intentional because you see him sort of throw his shoulder into it but I think that was him sort of protecting himself a bit. I hate these sprint finishes with turns, you can really appreciate their athleticism and raw power when they have a straight sprint finish.
Also a good point made by the NBC Sports commentators was that these guys are racing against each other 30+ times a year and there is absolutely no reason for Cavendish to do something like that, which he hasn't done in the past. Just food for thought.
Haha Cavendish throwing a hissy fit seems pretty normal now... in the past I found Cavendish's riding to greatly outweigh his somewhat crappy personality but this tour he has been somewhat disappointing on both fronts.
Life goes by pretty fast. If you don't stop and look around once in a while, and do whatever you want all the time, you could miss it.
