Skeeter is right. There has always been a degree of management / strategy, that is part of what makes F1 after all. However, the fact vettel didn't bother on Saturday then flew to 4th on Sunday is more representative that the regulations are too restrictive rather than the driver putting in an awesome drive.
If the race was 1 lap longer, Vettel would have come 2nd.
And Bernie said they were looking at providing additional sets of tyres for Friday, starting in Spain. Nothing about changing them or changing the allocation for races.
