Formula One World Champion Lewis Hamilton took to the wheel in a London black cab to back an anti-drink-drive campaign on Wednesday.
According to The Mirror, Hamilton teamed up with double world champion Mika Hakkinen for the trip as part of the Johnnie Walker responsible drinking programme.
The pair hailed the public transport drivers who get people home safely as "the real champions" behind the wheel.
Hamilton said: "Our message is simple - never drink and drive. If you are out celebrating, use a designated driver, whether that is a taxi, bus, tube or train driver or a friend who doesn't drink that evening.
Hakkinen said: "Lewis and I want to use our profiles positively and try to change attitudes. It's great we've been able to come to London and highlight the real champions, the people who get us home safely every day of the week."
The champions drove black cabs across London's Tower Bridge towards City Hall to join forces with professional drivers from Transport for London.
Last year, 460 people were killed and approximately 1,750 seriously injured in the UK as a result of drinking.
