Under that interpretation, how do you tag a lane that both continues and branches off as an exit, but doesn't have signage that it continues? <br class="">

<div class="">According to the wiki, "none" means that there are no indications on the lane. The value "none;slight_right" says that there are both no indications and a slight right indication on the lane, which is of course impossible. These "scripted" edits are therefore a correct interpretation of the original tagging. The problem here is that the original tagging was incorrect.</div><div class=""><br class=""></div><div class="">On Aug 24, 2016, at 7:24 PM, Jack Burke <<a href="mailto:burkejf3@gmail.com" class="">burkejf3@gmail.com</a>> wrote:<br class=""><br class=""></div><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class="">And I, too, have a preference for using "none" instead of leaving and endless line of "|||||||||" to try to parse.

Do they think that "none" is an invalid option and are replacing it<br class="">
with a blank globally? If so, this should be shut down immediately.<br class="">
"none" and blank are both valid values and while I wouldn't mind<br class="">
