Bit of dramatisation and conspiracy theory really though. Imagine if he did intentionally take him out to take the championship. I don't think any of it would end well. Like I said, rosbergs nest chance was to go for the win and hope Lewis had a problem. Instead he ended up over cooking his start, spun his tires up and Lewis was laughing all the way snatching the lead from him. What else is Lewis going to do there? Hang back also just in case roseberg wants to attempt to take him out? "ooh nico gas had a crap start, I better hang back too". On that front line a guarantee no one is considering anything other than getting into that first corner as fast as possible and if that means you're ahead of everyone else then happy days as you're less likely to have a collision.
