[Tagging] Mapping as two ways or one, u-turns

[Erik Johansson]

There is nothing separating this road yet it is mapped as two ways:

This is done for routers. Imagine you want to go from the marker to
number 117, as it is mapped today the router will know that you can't
go back on the same street directly. How can this be mapped with out
mapping this as two ways, as it's said in the Editing standards:
