He must have went straight home after crashing out in Malaysia because Kimi was fkin awful there.
There are 4-5 of them all driving at a similar level I think. Alonso has probably been at his best in 2 races but still made an error in Malaysia that cost him dearly. Kimi has been good in 2 races, bad in 1. Hamilton has been driving well considering it's a new team and can't really complain about Vettel's performances either. Button has done well in a car that isn't good enough to challenge for a win.
Di Resta has surprised me as well, he's been a lot better this year.
I would put Kimis Malaysia more in the car than himself tbh, which wasn't that surprising remembering how horribly bad Lotus was on anything close to wet weather last season, and I expect to see similar races from him in other wet'ish races this season
