well let's look at Hulkrushenberg.
beaten quite comprehensively by Barrichello and quite unimpressive in a team he was loved and supported.
Australia=one of three cars taken out by a spinning Koba? lol, Kobayashi's front wing failure was down to design flaw. Kobayashi was victim as well. what's funny is Kobayashi himself was victim of crush like by Liuzzi too that year, so why ignore? pole at Sao Paulo? yeah in a wet and drying condition. just perfect timing.
what's funny is you say "crushed the overrated DiResta". Crushing overrated driver as a proof he's special?
Anyway he beat Di Resta who's beaten by Sutil who was comfortably beaten by Fisi who was destroyed by Alonso.
outperforming Guti, who's a rookie who's considered mediocre at best, doesnt prove anything.
now looking at Kobayashi, just 2012 alone;
his rear wing flap was damaged at T1 of opening lap by Perez and was flipfloping for whole race
his rear damper was slowly failing from in the middle of FP3. Team could identify the problem only because he kept insisting sth was defo wrong with rear suspension for several hours after Quali.
In the race, he asked for wet tyres on lap 3 or so but team ordered him to stay out (eventually pitting lap 9 or so). When it was drying up, he asked for dry tyres earlier but again team ordered him to stay out. Eventually his brake failed and had to retire.
good quali. But during support race on sunday morning, a car put oil patch exactly on his starting position, which hindered his start apparently.
his Q2 best lap was set with right rear tyre being sprayed with leaking oil from his car. Without which he wouldve run at Q3 and started from better position and might have finished higher.
In the race, team gave him slow pitstops, releasing him behind he wouldve overtaken by under-cutting, hence he had to risk overtaking on track. Besides, Sauber car had such poor traction that he couldnt come close even with DRS open, hence he had to risk at hairpin.
taken off at St devote several sec after the start. Also, he insisted different tyre choice for Quali than team's recommendation. and it turns out that his choice seemed to be correct.
stuck behind Kimi and di Resta for long time at critical point of the race, which cost him 15sec at minimum. Plus team changed strategy from 2 stopper to 1 stopper in the middle of the race. SS>S 1 stopper was the strategy that was meant to fail in the first place. Plus, before the race, he insisted 1 stopper strongly, same as his teammate's, but the team denied it.
sure he crushed into Massa eventually, but again team gave him slow pitstop releasing him behind slower cars, forcing him to take unnecessary risks.
Kamui's start was screwed, again by team's error in crutch setting on Kamui's car. Then both Kobayashi and Perez race at Spa was ruined by Gro. If not for the crutch issue, Kobayashi couldve escaped the incident (Perez was crashed out there too, but damage was bigger for Kamui who started from 2nd. Anyway Sauber lost big points there).
his KERS failed during Q2
He had rather severe trouble in KERS and downshifting during race
Besides above, he had minor bad lucks here and there, like slow pitstop (like 8sec instead of 5), questioning strategic call (earlier than planned pitstop despite his good pace), all resulted in lost position and time at critical timing. Also races like Barcelona and Germany, he had to stuck behind slower car for many laps despite having pace and good strategy. Kamui just is without luck, almost miracle-esque.
"In short his Pre F1 and F1 resume is very strong..he's only 26,yet hes no rookie...has driven 3 seasons in F1 which makes him experienced enough to step into a Ferrari..a couple of years with Alonso will only help him improve more..and when the Spaniard moves on/retires/ is replaced,NH would be there to step into his shoes."
well I'd say exacly the same for Kobayashi.
