Would have thought 2 would be more likely, given that they tend to be 
two on each carriageway except in urban areas and where additional lanes 
may be required.
Mind you it's a while since I drove on one as I tend to avoid them where 
possible, rather take the scenic route.

Look at a new key for this rather than modifying the 4wd_only key.

Don't reinvent the wheel either there is a classification system for this:

http://www.4wdqld.com.au/track-classification.html
http://parkweb.vic.gov.au/iconic-four-wheel-drives/track-classification

so something like:

4wd:scale=easy/medium/difficult/very-difficult

when rendered next to the 4wd_only key use the appropriate icon from the 
above.

corrugated is intermittent, depends on when the road/track was last 
graded and probably should be part of smoothness. The surface is still 
gravel/dirt/ground,etc.

surface=mud is already in the wiki

surface=rock is probably better than rocky
