That would be a fun experiment. It's basically just a magnet on your spokes and the computer calculates the RPM. You would need to get the right radius setting for the car wheel though. Some are adjustable so this might be possible.
That rally monitor seems to do the same thing with a traditional wheel speed sensor.
