We have just seen a replay of the start. Nothing too complicated about how Bottas found his way to the front.
Hamilton got the a sluggish start, Bottas whipped ahead of him and Verstappen after an initial good get-away suddenly lost power and slide back through the pack before being shunted out into the gravel.
Max Verstappen is stomping back to the pitlane with a face like thunder.
Behind the safety car, it is Bottas in the lead, Hamilton second, with Charles Leclerc's Ferrari third and Alex Albon in fourth.
I did not see that coming.
Verstappen out of Tuscan Grand Prix
quixoticqeek: Oh dear Max. You really wanna avoid that gravel, it's not good you know...
James Townsend: Well that was a start at a new track not raced in F1 before for sure...
Kayleigh: Sainz getting spinning lesson from Vettel before his Ferrari move.

I think Vettel will have to come back into the pits. Grosjean is lucky to have got out of the gravel.
It was a chaotic start. Carlos Sainz's McLaren was spun, but got back racing. Sebastian Vettel is in the Ferrari garage for a new nose.
Pierre Gasly is out of the race after a tangle with Kimi Raikonnen...

High temperatures and the likelihood of teams pushing for a one-stop race means tyre management. But what is actually happening when the tyres get hot? For the tech-heads out there, here’s the explanation.
At high temperature the compound loses its modulus - a measure of its overall toughness and extrusion resistance. As a result, it loses grip. High temperatures also increase pressure - a problem because the starting pressure is regulated to safeguard the structural integrity of the tyre, this Pirelli’s mechanism to prevent blow-outs. And high temperature reduces the contact patch, so there is less rubber in contact with the track, which means less grip. Less rubber means the strip in contract with the track is under more strain, and it heats up further, creating blistering, vibrations and further loss of grip.
As the engines fire up, here is your full grid rundown:
1. Lewis Hamilton
2. Valtteri Bottas
3. Max Verstappen
4. Alex Albon
5. Charles Leclerc
6. Lance Stroll
7. Sergio Perez (one place grid penalty taken)
8. Daniel Ricciardo
9. Carlos Sainz
10. Esteban Ocon
11. Lando Norris

14. Sebastian Vettel

The panic has calmed down with Verstappen. When it is a software issue it is such a murky thing to comprehend. You can't fix software with your hands!

It is a huge celebration for Ferrari. 1,000 grand prix is pretty incredible. Today they are up against Red Bull. Imagine asking someone at the 1950 Monaco Grand Prix what an energy drink is.
Tune into radio commentary at the top of this page.
The Red Bull crew look just about content that they have fixed whatever was up with Max Verstappen's car. I think I remember that look in the eyes of a bloke I bought a 15-year-old Fiesta off once.
Let's see.

Lewis Hamilton is harnessed into the Mercedes cockpit.
It is going to be a gruelling afternoon for the whole of the grid, with big G-forces and the mercury pushing 30 C.
Reverse grids in Formula 1 - good or bad idea?
Jose Thorpe: Mercedes are champions for the past six years based on merit and not through gambling. Reverse grid race does not even add up in here. Other teams should also come up with cars capable of challenging the Mercedes. Red Bull and Ferrari were there for few years as well.
Chris Lord: Reverse grids and different formats of qualifying should only apply at certain tracks. Reverse grids would result in crash galore at Monaco and street tracks, and you aren’t a racing fan if thats what you want.
loekieprivat: I agree with Toto Wolff that reverse grid is not a good idea. It can also create dangerous situations . But I disagree with his "best man and best machine wins". That should read "best driver".
There is a crowd of concerned Red Bull faces around the rear of Max Verstappen's car.
It looks like the engine has overheated. A plume of white steam is spitting out into the Tuscan air.
All hands to the pump with mechanics leaning over each other to get involved with resolving the problem.
