In todays qualifying Nico Hulkenberg and Kevin Magnussen didn't get grid penalty since they slowed down enough under yellow flags while three other people got punished:

A statement from the stewards read: "Although the driver went 'green' [setting a personal best time] in the sector where the double yellow flags were displayed, the telemetry clearly demonstrated he had decelerated on approaching the flag point and that his speed reduced in the yellow flag sector."
How [insert colourful expression here] can you claim with margins in F1 that someone slows speed down significantly and at the same time improves his sector time? Since he improved his time the slowing down could only happen for a fraction of a second, something a bystander can't see. Is it that much safer if you crash on a parked car at 256km/h instead of 257km/h? I say that in dry track it's physically impossible to improve time (which is already within 107% rule) if you slow down enough for yellow flags and this is a big fat double standard in all the fancy safety speak amongst F1.
