he choked the title
The full story is yet to come out (and may never will), but if you look for it there's plenty of noise out there that Lewis not winning that rookie-season title had more to do with Max Mosley vs Ron Dennis politics than it did Lewis. There were some odd decisions by the McLaren pitwall in the last two races of that season, there's a theory out there that giving Kimi the best shot at snatching the title was the price of avoiding a full ban from the following season for the spygate thing.
