Motorists

Eight motorists drove to church one morning. 
Their respective houses and churches, together with the only roads available (the dotted lines), are shown. 
One went from his house A to his church A, another from his house B to his church B, another from C to C, and so on, but it was afterwards found that no driver ever crossed the track of another car.
How is this done?
