Aviva "The Aviva extreme driving challenge" by Adam & Eve/DDB

Formula One's David Coulthard shifts into rogue cab driver mode in an ad highlighting the money-saving benefits of safe driving.

Coulthard disguises himself with a fake beard and moustache to pose as a dodgy minicab driver who picks up two unsuspecting passengers, terrifying them with a series of extreme driving manoeuvres before demanding £53 for the fare.

The film is running on TV and social media.

Previous campaigns for the brand starred comedian Paul Whitehouse dressed in a range of guises, including a goth and a leather-clad biker.
