Engadget alerted me to this GPS data logger from Spark Fun Electronics.
The device records up to 440 hours of data to a 256MB SD card in either a simple text file or KML-compatible format that you can display in Google Earth.

You can see what lane Casey was in! When he stopped at the light, his data points piled up. Fancy. Real fancy. Speed is also datalogged – it’s like Big Brother in the palm of your hand…
