I recall watching the finish of the RAC Rally at York Racecourse in 1975 or thereabouts, as a schoolboy. (Yes, I was sneaking off, but the rest of my class had also sneaked off to watch York City FC play Southampton in the FA cup.)

The BBC camera team kept asking bystanders to shuffle sideways, to conceal the logos of the Fiat Abart Racing Team from a shockable public.
