It's pretty amazing that Hamilton is ahead now in the Championship, despite being far worse affected by technical issues and team-mate related issues than Rosberg over the course of the season.
7 wins versus 4 is pretty telling when you think that he would have definitely also had the win in Melbourne and that he'd also won in Monte Carlo if it hadn't been for Rosberg's little qualifying "mishap". Rosberg would of course have won at Silverstone, but then, Hamilton would have had a lot of extra points in Spa, Hungary and Canada. And Germany may well have gone Hamilton's way too.
If everything would be about even, Hamilton would now be at least 30 points or so clear at the top.
