Mercedes driver Valtteri Bottas: "We all just want to get going. We are waiting for the decision to get a green light, nothing else we can do really.
"Melbourne was a positive start. It wasn't one of my best weekends but there are still plenty of races to go."

They did get the L eventually...
That group of fans have found the L and added it to the rest to spell out Vettel's name alongside the stand.
Sebastian Vettel, watching the whole thing on a monitor, laughs and gives a thumbs up to the camera, prompting cheers from the stands.
Solid gold live text commentating, this.
THEY'VE FOUND THE L!

A fair few of the drivers are steadfastly remaining in their cars. Could be there for a while, lads.
Vettel, actually, is finding great amusement in watching a group of fans putting up a banner spelling out his name. They've got the V E T T E up, but have lost the L!
Vettel has a chuckle as they frantically look under the seats around them.
If this fog doesn't lift at all through the weekend we could end up with the very bizarre situation of no qualifying and even no race. Unprecedented.

Race director Charlie Whiting: "At the moment the helicopter can't land at the hospital. It looks reasonable at the circuit but they can't land in downtown Shanghai. We get news from the airport every 10 minutes.
"If it doesn't clear there will be no practice, we have a fixed end and if it does not clear by then there will be no P2."
Second practice is proving to be the biggest anticlimax since...well first practice.

McLaren are showing off a new T-wing design today (or would be if we could see some cars on the track) and it has so far been likened to a paperclip, coat hanger and TV aerial.

The lack of on track action is reminiscent of final practice for the United States Grand Prix two years ago.
On that occasion, Daniel Ricciardo and Daniil Kvyat entertained us all with a bit of a rain dance. Can we expect any similar high jinx this time?
"No tricks," says Ricciardo. "No plans, I don't know if Max Verstappen has the same horrible moves as Daniil had!
"I'd love to be out there, so I am just hoping this smog clears."
Image source, Getty ImagesOh my, these pictures from before the 1999 Malaysia Grand Prix get even better.
Apologies, this kind of space filling is only going to increase the longer nothing goes on on the track.
There's no change in the weather. Still misty, still no cars allowed on the circuit.
Williams chief technical officer Paddy Lowe: " I'll never forget 2009, the first year with KERS and the high voltage in those systems, we were still learning our way around them and then we had this race where the cars were literally swimming through inches of water. I remember a Ferrari was abandoned and no-one dared touch it.
"It was incredibly hot there. My feet started to burn one year just standing on the tarmac and I'll miss it."
Memorable Malaysia moments
Image source, Getty ImagesWhile we wait for any kind of on track action, let's remember some of the great Malaysian Grand Prix moments. Giancarlo Fisichella and Alexander Wurz standing in front of the Petronas Towers is not one of them, but I couldn't resist the chance to get this picture of stood in their oversize shirts back at the first race in 1999.

Toto Wolff on the loss of the Malaysian Grand Prix from the calendar: "It is a bit of a blow. It was one of the great circuits. For us emotionally it is a bit tough to overcome because it is a home grand prix."

Yeah, it is still very, very misty.
Unless a massive gust of wind suddenly appears from nowhere I can only see second practice panning out a lot like first practice did.
