Suffix both_ways is misleading

The suffix both_ways seem to be misleading. Especially in the US *:both_ways is misused instead of *:forward and *:backward with identical tag value.

For example most values of turn:lanes:both_ways, which are shown by taginfo, are due to such misuse. - Slhh (talk) 01:39, 12 June 2016 (UTC)

Redefining *:forward and *:backward meaning

The proposal seems to redefine the meaning of these suffices to single direction lines, but this is not clearly defined. The usage in database seem to be varying. - Slhh (talk) 01:39, 12 June 2016 (UTC)

Direction dependent properties

Traffic signs are direction dependent, therefore, the properties of lanes for both directions are likely direction dependent. In case *:forward is restricting the meaning to lanes running in forward direction only, it is not compatible to using *:both_ways:forward. - Slhh (talk) 01:39, 12 June 2016 (UTC)

Using both_ways within a junction

Both Ways Example 1.jpeg

The left turn lanes might look like a shared lane for both directions at a glance, but this is functionally wrong. In fact both left turn lanes can be used simultaneously because they turn out before the other one is reached.
