Jun.21 (GMM) Even three full weeks and a grand prix after the Red Bull teammates' crash, details of the Turkish incident are still leaking out.

With controversy and intrigue having surrounded their crash whilst leading May's Istanbul race, the latest tidbit is revealed by Germany's Auto Motor und Sport.

The report claims that although Sebastian Vettel was roundly criticised for jinking to the right before contacting the sister RB6, Mark Webber could have followed the advice of his race engineer and perhaps avoided the incident altogether.

It recently emerged that engineer Ciaron Pilbeam radioed Webber on the lap of the crash to tell the Australian that, although his engine was turned down, he could "use your overtake button for a boost on the straight" to repel an attack from Vettel.

Even when in a fuel-saving engine mode, the button temporarily delivers the full 18,000rpm of power.

But Auto Motor und Sport reports that Webber did not know whether he should press the button just once, or for the duration of the power boost, with the "confusion in the cockpit certainly not helping the situation (with Vettel) at 310kph".
