Although He's still doing some Boogie Nights Moves, presumably?
Just a very brief Jot', as Bloody 'Ol F1 Grizzled Journo' Joe Saward would say... About Bloody 'Ol Jense', nee Jenson Button. Having listened to thou story from Reuters 'bout Button possibly having driven his 2009 Formula 1 World Championship mount, Thee Brawn BGP 001 for the very last time at this year's British Grand Prix.
As the car owned by Ross Brawn ran some Demonstration laps at Silverstone with Button behind the wheel, in what sounds like it might be the last time the 2009 Formula 1 World Champion gets to drive his '09 F1 Championship winning chassis? (#BGP 001-02)
Since according to the story, the Brawn BGP 01 in Questione is the only remaining chassis with a functional Gearbox, not to mention that the Carbon Fibre suspension Uprights are no longer produceable, with Thar Molds being Chucked long ago.
Meanwhile, it's funny how I still recall that Jense' needed to file a lawsuit against Mercedes, who'd taken over the Formula 1 team from Ross Brawn, after he'd previously Contractually agreed Button could keep one of the three BGP 001 chassis if he won that year's F1 Championship.
Although Funny how Button laments in the Reuters article how he didn't know he was getting a car without any gearbox internals... Or as 'Ol Hobbo' (David Hobbs) would say, A Gearbox Full 'O Neutrals; Hya!
