In Hungary Alonso’s car was behind BMW thanks to a FIA decision, not Alonso lack of pace.
In Istanbul it was a tyre bad choice as Alonso recognised as his own mistake after Q3 was over. Alonso was quicker with the option tyre on the first attempt.
Kimi had also a mistake on last attempt; still he managed to past Hamilton at the beginning and set the fastest lap at the very end. Even so he was unable to pass Massa.
I don’t know what you mean by "trouble free", is there any moment when driving a F1 catalogued as "trouble free", maybe when the 'safety car mode' is set on the mappings...
