Talk:Proposed features/Suffix both ways
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.
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
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.
