San Francisco Bay Area Traffic Maps: (map511.atspace.com) Real time traffic maps for the San Francisco area. There's an overview map and detailed maps of the East and South Bay, but not for San Francisco, the Peninsula or Marin which have plenty of traffic too. The maps are "optimized for Palm Treo 650 and 700p mobile devices" so they are a big 306px wide and backed by an html image map so that touch screen users can tap on the overview map to open a detailed sector map. There are also text links to the sector maps so the site is usable on any phone that can display images that large. Opera Mini however gets confused by the image map and breaks the single image into three separate images arranged in a geographically illogical order.
