The new F1 Race Director has come in looking to stamp his mark - but he's picked some interesting places to try and do that.
Earlier in the week it was reiterated that drivers aren't allowed to wear jewellery or body piercings - a rule immediately defied by Lewis Hamilton who said he'd have to get his ears chopped off to remove his earrings.
Now it's come out that there's a stoush about drivers underwear, with drivers told on the eve of the Australian Grand Prix that they must wear non-flammable underwear - and no one's sure if that will involve race officials checking or not.
BBC Formula 1 commentator Jack Nicholls joined Mike Hosking.
