Are you able to "rank up" your drivers and staff every time you train them or race with them? Do their ratings gradually increase throughout time? For example, my driver, Favio Maneiro, is rated with a 3. Over time, after winning some races, if that happens, or even just completing races, will his rating go up? I personally think that he has a lot of racing potential for my team and I want to keep him even as my team and I "level up".
Thanks. :)
PS. On that note, I was also wondering what the green and blue bars indicate under the driver's name.
