For drivers like Kimi and Alonso who's motivation is to win races, they don't really have any motivation to race at the moment. Kimi more so, seeing as his relationship with Lotus has gone to shit.
This is good and bad news for Valsecchi. He is lucky that he gets the chance to race, but I have a bad feeling he won't do so well because he basically has almost never driven the car before. He will be judged very hard on these 2 performances and they could make or break his career.
