Currently, I have the non-parallel spots marked as a lot. To my mind, <br>

Well it's certainly not a parking *lane*; you clearly are not meant to <br>
possibly drive through it. I was thinking that the fact the parking <br>
spaces are arranged so as to not occlude traffic was what was inclining <br>
me to model it as a "lot".<br></blockquote><div><br></div><div>I take the marked parking spaces as a very strong hint that it's a lot.</div><div>It still depends on surrounding circumstances and context, but if they're</div><div>marked as parking spaces the purpose of those areas of hard paving is</div><div>for parking.

Really, it's the notion of a parking lot for which the aisle is also a <br>
main road that's throwing me...<br></blockquote><div><br></div><div>The main road is a WIDE parking aisle. :) Alternatively, it's a parking lot</div><div>with a very wide entrance. Yeah, it's a bit weird, but how else do you</div><div>represent the parking area in a way that indicates there isn't a narrow</div><div>entrance from which you then fan out into parking spaces but that</div><div>each parking space may be entered directly from the main road?</div><div><br></div><div>As far as I can determine, the closest way we have of representing</div><div>the situation is a parking lot that abuts the highway.

That's not</div><div>really how it is.</div><div><br></div><div>3) A parking lot that joins the highway.

<br>
Yeah, that line of thinking is similar in effect to asking if it <br>
occludes normal traffic flow. Different questions, but likely to have <br>
the same answer.<br></blockquote><div><br></div><div>Same question, different phrasing. <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Well, there's an easy solution to that; map the spaces, also ;-)</blockquote><div><br></div><div>Yeah, but the spaces don't render. Oh wow! I just checked one of your</div><div>later examples and parking spaces now render. I'd given up on hoping that</div><div>they would render.

<br>
Agreed (on the 'looking ugly').</blockquote><div><br></div><div>:) <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
Anyway, your example would be much more sane if the entire road had a <br>
mapped area, rather than just the little piece by the parking lot.<br></blockquote><div><br></div><div>Yeah, but that ugly bit is also a lowered sidewalk. That car park has a very,</div><div>very wide entrance (the width of the car park itself). What I did was a</div><div>compromise, and it's ugly. But without mapping (and rendering) sidewalks,</div><div>and mapping (and rendering) the true widths of roads, there's no good</div><div>way of handling it, just a variety of bad ways.<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

...and to be honest, another argument for modeling as lots is that the <br>
parking_lane tagging is rather more obtuse...<br></blockquote><div><br></div><div>There is that. Which is why I tend not to bother with it.
