Just looking at the results thus far this season and I noticed a couple of things.
People like to bash Bruno Senna as not being a good driver but he's out raced Maldonado 10-5. If it weren't for ET's one-off win he would be absolutely crushing him in the points. I think if he could just get more out of the car in qualifying he'd be doing well. He's got good race-craft. Unfortunately he'll most likely lose his seat next season.
The other thing is how amazing Kimi has done so far. Only one race without points. The only driver in the top 6 to not have won, the rest have two or more wins. Yet he's third in the championship. This is why it really doesn't matter that he's terrible at interviews and press functions.
