In testing Kimi Räikkönen had same lap times as Kyle Busch in KBM truck race will be different but Kimi sure has skills to learn fast. It's not like rally where you have to learn for years to even dreaming of getting to the top.
F1 is almost like squash, NASCAR is tennis and rally (WRC) is ping pong.
Im not one for conspiracy theories but I believe NASCAR didnt throw the caution on that final restart cause they new junior had a good lead and would probably win. Maybe Im wrong but thats certainly what it looked like.
