The two cars race neck-and-neck through the southern suburbs of London. But with only a few yards to go, Genevieve breaks down. As Ambrose's car is about to overtake it, its tyres become stuck in tramlines (London's tram network had closed in 1952, but many of the tracks were still in evidence when the film was made that same year) and it drives off in another direction. The brakes on "Genevieve" fail, and the car rolls a few yards onto Westminster Bridge, thus winning the bet.
