OK Li, you ask and you shall receive ! Here http://wiki.openstreetmap.org/wiki/User:Davo#Draft_4x4_road_proposal is my very early draft. You and everyone else is welcome to get stuck into it, I am not thin skinned !
The OSM proposal page says to to be verbose, no one need tell me to be verbose ! So if its too long, please indicate what needs removing. And obviously, error and omissions .... I am quite unhappy that it really ends up undercutting the 4wd_only tag, they can coexist but I wonder if they will if this is successful. Its a shame really, I like 4wd_only and have used it but as I developed my arguments it became clear to me that we need a finer grain and its probably easier to add levels to tracktype than it is to 4wd_only. And it will be easier to get these levels rendered if we go for tracktype.
