HIGH WAY should be fine, swim with it. only 1 camera on the corner, i mean if u drive 200-240km, its a corner for u.
Motorway from Mel to Bri, 16hrs, no police, no camera, u can stop in the middle of road, start from 0 to 240km, stop, then start again, a lots of fun. just be careful there are only few petrol station all the way through, and stupid animals.
