</span>They are not matching reality, can cause long detours and poor routing<br>
unless the mapper provides a lot of connections to the road. Remember<br>
normal pedestrians can cross wherever they want.<br></blockquote><div><br></div><div>Sounds like something any reasonable router should be able to take into account and recalculate against based on position. I can rodeo to the other side of an expressway and a couple freeways to hang a U-turn (with varying degrees of physical possibility or legal acceptability) in my region across the grass median but that doesn't necessarily mean that's a smart move that should be suggested to the average person with no regional experience. Likewise, I didn't know jaywalking wasn't a thing in terms of legal concepts in the UK until this thread and would be more prone to expect a more comfortable route to where other road users would explicitly expect me to take such an action.</div><div><br></div><div>Point is, the data should be on the assumption of a complete greenhorn or someone who doesn't necessarily understand how getting around a particular locale works is using the map.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
There is also the simple rendering issue, roads are already wide and<br>
are very close or clipping buildings. The sidewalk if mapped in<br>
position is likely to be hidden under the road.<br></blockquote><div><br></div><div>I'm not seeing how this is a data problem. It still routes, right?</div></div></div></div>
