Something similar happened back in the 70s. At the Australian Grand Prix one of the cars had the brand 'Durex' written all over it so to keep up public standards the tv director decided that no camera shots of the car would be broadcast. Unfortunately, that particular car was in the lead for most of the race and, I believe, eventually won it!

That's what gets me about the British government though. It stops tobacco advertising and is now talking of banning smoking in public places but the Goverment makes a fortune from the taxes imposed on both tobacco and alcohol.
