I know how you lot love a good conspiracy theory, so here goes

After qualifying in China, Vettel remained in his car for quite some time until parc ferme had emptied, where usually he loves to leap out and show everybody his finger.

Then in the race, both he and Webber did the same in parc ferme, remaining in the cockpit until the other drivers had cleared out of the way.

Is there a control or a gadget they don't want the others to see? Are they just playing mind games? Or was it just coincidence?

There. That's given us something to argue about in the three weeks until Turkey!
