I wonder if one could figure out other vehicle speeds from a dashboard camera. His method looks like it assumes a stationary view.

If you had an OBDII adapter and a camera this should be possible! I'm not sure if there is OBDII communication code for RPI, though

There is. There are obd boards that use the standard uarts, and dongles that use bluetooth that you can read from the pi. Here's one guy's project on it. http://fabcirablog.weebly.com/blog/reading-a-cars-obdii-port...
