Q1: If I upload a GPS track, that is a bike trail, and specify it as a bike trail in Potlatch, does it show up different?

Q2: Can people turn display of Bike routes on and off somehow? Will it clutter the map?

Q3: Will routing software try to route cars down it?

Q4: Which Cycleway should I choose? These are 8-10ft wide concrete paths used by people walking and bikes. I am guessing Cycle Lane is part of a road, but what are the "(NCN)" choices? Footpath? Byway? Basically created by small towns along streams and through parks. 2-5miles long, they do cross roads.

Q5: Does opensourcemap have an issue with a GPS track that occasionally doubles back to route a different branch?
