Some "cute" analysis regarding luck and bad luck so far ... :
1. Australia round :
Lewis : bad start; bad timing with the red flag; and then puts him on the back foot with the tyre strategy
Vettel : bad timing with the red flag; bad tyre strategy
Kimi : bad race strategy; PU issue
and now Rosberg: survives after a half bad start; takes advantages with the red flag when he switch tyres with the medium ones; got lucky with the brakes on final laps
2. Bahrein round :
Lewis : half bad start; got car damaged with Bottas incident, not his fault
Vettel : PU issue
Kimi : bad start, front wing damage then far to back to make a threat
and Rosberg : nice getaway and easy win
3. China round :
Lewis : previously a 5 grid penalty for a gearbox change; starts dead last due to an ERS issue; FW broke in the first lap incident without his fault, then-after he damaged suspension after that incident when he went into the gravel ... maybe here is his fault coz should he went easy afterward he would`t went to the gravel ... and another mistake of his own was that he should have start from the pit lane, as he recognized in Sky interview after the race ... yeah, in hindsight we could be all heroes
... the only good thing he did today was the start, as he stated and we saw in the TV replay footage ...
Vettel : half bad start and afterwards front wing damage and maybe more
Kimi : good start but too much speed entry in turn 2; car damage in collision with Vettel
now Ricci : very good start; bad luck with the blown tyre
and last, but not least Rosberg : half bad start; got luck with Ricci tyre issue
So how how many times he will be so lucky? Not many, IMHO
