I have no idea why they did it, but the Maserati segment was full of sounds taken from computer games. At the 15min mark (when the Stig exits the car) starts a theme from C&C Generals http://www.youtube.com/watch?v=FTjM2Kd2NX8#t=1m28s . Also right after the painting scene you can here a StarCraft Wraith (or Battlecruiser) laser and an unpacking Siege Tank, then another tank unpacking right when he says "and not everyone likes how the GTS looks" (13:30 in the rip). This is the stuff I'm 100% sure about, most likely there are more.
Usually it'd be pretty normal to cut out bits, but considering Anh did a stand up routine for the audience during the blackout in the studio, I think the production crew would have felt a little guilty.The Star In A Bog Standard Car segment took eleven and a half minutes. That is way too long to be spending on it. They could be using some of that time to the news, another car review or making the challenges longer.
We have a prime minister who deliberately slipped 'shitstorm' into an interview on TV at 6:30pm (TGA airs at 7:30pm) in an attempt to be on the level of the average Aussie, this is just another manifestation of that sort of thinking I'd guess.Something else I noticed is that the language seemed to be creeping towards more immature boundaries. I don't know if TG-Aus was in a later time-slot or something, but the number of vulgarities were noticeable.
