Eric Steward told police he failed to stop because he "liked to drive".
Visiting friends in Yass, a country town south of Sydney in New South Wales state, Mr Steward left to buy a newspaper on Monday morning.
More than eight hours later, after taking a wrong turn on the highway, he asked Victoria state police for help.
