Mr Steward told police he failed to stop because he "liked to drive".
Mr Steward was visiting friends in Yass and went out to buy a newspaper on Monday morning. After more than eight hours and after taking a wrong turn on the highway he asked Victoria state police for help.
I just went out on the road to have a drive, a nice peaceful quiet drive.
I didn't know where I was going but I knew it was somewhere, and with a bit of luck I would eventually find my wife again.
