Google Earth supports feature/layer import via an open XML standard, "KML". So, if you or anyone publish geolocatable features in this format, your instance of Google Earth can 'file:load' the feature layer, and display it in your instance of Google Earth, correctly earth located. It will appear as a feature layer, and you can also selectively enable/disable individual features, or classes of features, depending on how you publish/create the KML file. The requirement is, publishing the feature data using the KML standard schema, which is described here:
http://code.google.com/apis/kml/documentation/
There are alot of published KML features available, many of them weather related, like radar sites. Also, MODIS fire detection polygons. A little time studying the KML doc, and you can publish your own geolocatable stuff, just be creating the right KML file.
What struck me with this story is... it really wasn't necessary to actually drive with a logging GPS, to create what he did. (Did he really do that? Maybe he did.) It would be possible to publish the feature track he wanted as KML, and just display the KML as a feature layer.
