I downloaded Google Earth for Mac and am playing with it. You can "Record a Tour" and save and play it back. There's an Earth browser plugin, so you don't need to run a separate program - it seems a bit clunky in FF.

38.160894,-122.45898 is around Turn 2. Turn on Street View in Google Earth to follow the car.

A great way to waste a few hours on a Friday, but I've got chores to do (taking a vacation day today...). :-)

Cheers,
Scott.
