Actually he didn't have KERS at all but keep selectively leaving out facts to support your case if you have to.
I like MW just fine, he is hardly the second coming of christ and he is hardly the worst driver in the field. He has worked his arse off, he has also had lots of luck, he has also had lots of bad luck, he had a charmed existence in Australia in karting days to get him to Europe ahead of more talented karters (at that stage) due to support from his family. He has been hamstrung by his frame as well.
There are no prizes for guessing that F1 does not attract the best drivers in the world, it attracts the best, richest, midgets. All get there due to support from somewhere, rarely is it on talent alone.
The last race worked out despite the poor qualifying, nothing more nothing less. Good on him for getting a good result out of a bad position.
It seems for MW he is damned if he does well, he is damned if he doesn't.
