OK, I have to recognise that my "proposed proposal" is not attracting any support. So I will walk away. However, that leaves the problem unsolved and , I still think, dangerously so.
Are there any alternatives folks ? Should we (ie in Australia) encourage people to use smoothness= for example ? I hate the tag name and the values associated with it but maybe its the only game in town ? There are already considerably more horrible, very_horrible and impassable values set against smoothness than 4wd_Only tags and by a considerable factor. It does offer a degree of "fine grain" against 4wd_only's 'yes' or not there. However, (eg) OSM website map ignores smoothness= (unlike tracktype) but that may be becuse not enough people are complaining about it. But I must say, I would not feel anywhere near as confident asking renderers about smoothness= as I would about an extended tracktype=. Please consider....

Indeed, but as long as mappers present the renderers with a mismash of data, we can expect no better ! > http://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer No, I don't really think my proposal fits into this catagory, but it does take a more pragmatic view than many OSMs would.

My plan was always to seek the simplest way through a very complicated maze. If its still not simple enough, so be it ! > ....

I have tried and failed with tracktype=, the 'proposed' ones mentioned above are all either abandonded or should be. mtb is about mountain bikes and so on. we are really not addressing this problem folks ! > Although this issue does affect Australia due to the nature of the > outback, it is a global issue.

No, to be realistic, if I cannot get any support here in Oz, little hope of doing so elsewhere. Sorry about any awkard editing here, using an android device as I am away and left my laptop powersupply at home! David
