I happy this discussion comes up and I would like to chime in on this discussion.
Reviewing the map reveals that many places roads seems to have too high of a classification, misleading people to use roads that are not meant for a lot of traffic.
>From an overall perspective the classification of roads should be used to guide people which roads to prefer.
Looking at the length of road of the different types this seem to underline the problem.
Motorway, Trunk, Primary, secondary and tertiary should only be a tiny fraction of all the roads.
The bulk of the roads should be of lesser importance, such as unclassified and residential.
Assuming that all motorway, trunk, primary, secondary and tertiary roads have been mapped long ago, newbies should only be concerned with the lower classes of roads.
I suggest the out come of this discussion will be a series of photos of typical roads and how to tag them.
Potlatch 2.0 is in the works and will simplify tagging of roads significantly. My hope is that we can update the newbie instructions so that everybody would feel comfortable tagging and naming roads.
I have started a document already for this purpose so this discussion is very welcome :-)

I feel we should simplify it (although not too much), not everything
here is applicable:
http://wiki.openstreetmap.org/wiki/Key:highway
Another example, I don't feel like using the tag living_street.
Here's the highway length stats to give us a general idea what highway
tags are currently in use:
primary 13237678m
residential 12304569m
secondary 5340661m
road 3958559m
tertiary 3578034m
unclassified 3040564m
trunk 2262544m
service 856653m
track 803020m
motorway 558710m
footway 220230m
path 179135m
motorway_link 71836m
trunk_link 37981m
primary_link 32565m
cycleway 27131m
construction 25302m
pedestrian 14174m
steps 3520m
secondary_link 2660m
raceway 1542m
living_street 1473m
proposed 526m
ford 277m
old road 124m
Alley 101m

The road tag can be used for roads that have no actual road types, as proposed/planned.
