During my epic bike ride yesterday, there was one section of Nimitz Hwy that I found to be especially scary.  On google maps it's marked with a green dotted line.  There is no legend/key on the map, and my personal "intuition" is that this mean something like "ok, but not great, for bicycles".  Attempting to ride there, it was clearly evil to me.

Using the "report a problem" link (bottom right hand corner of google map display) I filed a request to either provide a key, change the color of the green dotted lines, or remove it from that section of road.

My previous experience with reporting problems turned out well.  I got them to add this section of bike path to the bicycle layer:

If you know about a more collaborative place for this kind of information, or know what dotted green lines really mean, please drop me a line.
