If it's <4m, you will be able to see continuous wear on the verge where people drive off the edge of the tarmac. At >4m there will only be wear for occasional large vehicles (tractor tracks, typically). At 6m there's usually a centre line.
I'd quite like some tags for these subtleties, but I wouldn't use the lanes tag (so not lanes=1.5) A few "standard" widths might not come amiss: maybe 3, 3.6, 4.2, 6? Some of you may remember that the OS criteria used to be 14ft (4.2m).
