I won't say the tune has changed; but, the lyrics seem to have!!

Live: Test day three 06:57 Some of you may have noticed that some pretty routine red flag stoppages seem to last a lot longer in Bahrain than they have in recent years during testing at European circuits.

Part of the reason for that is that the flatbed trucks used here don't have a mechanism attached to lift cars off the track.
So they have to be accompanied by a separate truck to put the car on there in the first place, and then wait for that truck to join it in the pits to return the car to the team in question...
11:50 Fortunately we haven't had too many stoppages today as the majority of the cars are getting more reliable.
But on the subject of red flags, EDD STRAW has been speaking to the Bahrain International Circuit operations director and clerk of the course Fayez Ramzy, who can offer an insight into the processes involved in vehicle recovery at these tests:
"We are under strict instructions not to touch the cars," he says. "When a car stops we red flag the session and wait until everyone is in the pits, then we pick up the team and take them to the car so they can recover it themselves and then we bring it back.
"We could easily restart sooner if the car was dropped outside or behind the garage, but the teams have insisted that they want the car into their garage from the front so we can't restart until it is inside. That is what takes the time."
11:54 The main reason the track recovery workers are not allowed to touch the cars is due to the new energy recovery systems being used this year.
Ramzy explains: "We had a red flag for half-an-hour this morning [when Chilton stopped], but the reason was that the car was not safe as far as ERS was concerned.
"Even the mechanics were standing there waiting for the car to be neutralised. Due to the evolution of the cars with the electrics, we don't touch the cars until the teams are out there and that is by their own request."
I'm betting it's a combination of these!
