Problems or trying to find that "just a bit extra" to get past? He didn't really "slip" or "slide" anywhere much. When did Grosjean set "fastest laptimes most of the race"? Kimi was some 8-10 secs (out of my memory, i'll watch the race again when i can and hope the laptime charts come up soon) behind Grosjean after both had pitted once, before Kimi pitted 2nd time, he did continously fastest times of the race, lap after lap after lap (which all were faster than Grosjeans fastest in the whole race, too)
