Why does the bloke drop the envelope when trying to post the letter?? Is it that the cars are so super de duper that they can fly while the bloke canny even post a letter?? I dont get it, surely that would mean you need to be daft to drive an astra?
It's the application of "Sod's Law". All the difficult stuff - doing the stunt driving goes without a hitch - while the simple task of wizzing a letter into the post box fails.
