  Either I would have a short bit of road with a width=3m while the 
pieces before and after had width=10m, or I would ignore it. Or I would 
put a single tree next to the road. Given that the road is the logical 
centerline and has a width=10m attached, the road then stretches around 
the single node tree.

Most of the above examples as before:
I would split the street in two oneways going around a single tree, as 
the street is effectively split physically here.

Funny one. Following your logic, each road in a forest would require 
that the forest be split in two pieces on each side of the road. 
Otherwise you would obviously imply that the whole road is covered with 
trees.
I would either ignore it. Or make a forest;layer=1 covering the area, or 
make the road going through a short tunnel.
