[OSM-newbies] Separating streets that don't join

[Isaac Wingfield]

Three questions about one thing:

In my neighborhood, I came across an "intersection" where the two  
streets don't actually join, though the map said they did. I separated  
them and added a "bollard" tag, because that's what is there; cyclists  
or pedestrians can go through just fine.

Problem is, at anything less than the highest zoom, the two still  
appear to join. See here:

http://www.openstreetmap.org/?lat=37.249885&lon=-121.910917&zoom=18&layers=B000FTF

How do I fix it so the streets stay separate at zoom levels a driver  
would likely use?

Second, the bollard shows up in the middle of the wrong street; it  
should be "between" Coralee and Little Branham. How do I arrange that?

And third, is it appropriate to add a nearly zero-length "cycle path"  
to show that bikes and pedestrians can go through, or is there a  
better way?
