Here I am replying to a dead thread again, but... While out mapping
trails in the rain a possible solution occurred to me (couldn't see
anything but the trail, so...)

My opinion: Tweak the geobase way to more closely match what you saw on
the ground.  Nuke the attribution tag -- it's no longer just their data.
Do leave the geobase:uuid, it still identifies the same bit(s) of road.
Change source to be "Geobase(r); GPS".  Toast the acquisitionTechnique
tag, and might as well toss the rest of the (not already mentioned)
geobase tags while you're at it -- the UUID uniquely identifies the
roads, the rest of the bits were just for us search-impaired humans.

1.5 lanes makes sense to me.  If there's a way to specify a width in
meters, you could do that too (or instead?).

Whatever you feel is appropriate, of course :)  I'm sure you've already
done so, but perhaps my musings are useful to you or someone else.

peace,
