This bookmarklet can create a GPX file based on driving directions, an address search or a local search. The GPX file will contain a route, a single waypoint, or up to ten waypoints, respectively.

GPS Visualizer is a free, easy-to-use online utility that creates maps and profiles from GPS data (tracks and waypoints, including GPX files), street addresses, or simple coordinates. Use it to see where youve been, plan where youre going, or visualize geographic data (business locations, scientific observations, events, customers, real estate, geotagged photos, "GPS drawing," etc.).
