This image displays a potential rendering for the proposed OpenStreetMap tag cycleway=buffered_lane when it is used in conjunction with a variety of highway=* tags.  I created and am uploading this image so that I can use it for my proposal on the OSM wiki, but am glad to add it to the public domain for anyone that can find additional uses for it (perhaps other OSM users!).
