Again, look at starting grid positions and finishes, bianchi is faster than the slowest guys but he was held up by Pic.
At the moment I made the teams like this.
Tier 1: Red Bull slightly better than Ferrari ((With Vettel same skill as Alonso) > (Massa = Webber))
Tier 2: Lotus and Mercedes, not sure which car is better, I think mercedes so I made this even by improving Kimi's skill and decreasing Grosjean's.
Tier 3: Force India, they got the pace, im sure of that. (Sutil > Di Resta)
Tier 4: Sauber and Mclaren , Both have a good driver and a bad driver according to myself. (Button = Hulkenberg) > Perez > Gutierrez
Tier 5: Williams and Toro Rosso , Williams, havent seen them yet this year? And Toro Rosso might be better im not sure, gonna improve their driver skills a bit.
Tier 6: Caterham and Marussia, both teams seems to have the same pace.
Bianchi >>>> Pic > (vdGarde = Chilton)
