[Tagging] trees and waterways

Tagging oneway=yes on a motorway is an example of tagging a special case.  The general assumption on roads is that they are two-way unless tagged otherwise.  Tagging the motorway as oneway=yes makes sure that routing calculations will work correctly.  Sections of motorways sometimes become two-way (usually with a safety barrier down the middle) when the other half of the motorway is closed for road construction.

But, in my experience, we do put oneway=yes on every motorway.
