Sure I used a shortcut here. :)

But most of the values of the highway tag were corresponding to a type
of road: motorway would be 2x2 with central seperator, trunk would be
mostly the same but with the possibility of smaller roads directly
leading onto the trunk (no sliproad), etc.
I know that the trunk value is the one that forced us to consider the
highway tag a bit differently than what was on the map features at the
time, because we have nothing like that. And it's probably the same
for other countries. So we used the highway tag to describe the
importance in the road network.
