In whom I trust
The OECD has defined[2] a motorway as:
French Equivalent: Autoroute
Road, specially designed and built for motor traffic, which does not serve properties bordering on it, and which:
(a) is provided, except at special points or temporarily, with separate carriageways for the two directions of traffic, separated from each other, either by a dividing strip not intended for traffic, or exceptionally by other means;
(b) does not cross at level with any road, railway or tramway track, or footpath;
(c) is specially sign-posted as a motorway and is reserved for specific categories of road motor vehicles.
Entry and exit lanes of motorways are included irrespectively of the location of the sign-posts. Urban motorways are also included.
Maybe one of these is not true for Australian motorways, or the data I used was not reliable, if this is the case, I apologize.
We have freeways that meet those criteria. So the data is wrong then.
