BBC F1 pit-lane reporter Tom Clarkson: "The re-introduction of GPS this year is proving very useful for the teams. Every car is fitted with a transponder, which allows the teams to monitor the pace of their rivals.
"It's even possible for them to produce an overlay of another car's fastest lap and work out where it's faster or slower relative to theirs. Perhaps now, as we start to see some low-fuel runs this afternoon, this will take on even more significance."
Ian McCormack: Ask Bernie if we can have triple points in first three races. The other teams could possibly get a head start before RBR come good!
