We also need to take into account that accelerometers measure
acceleration. If you accelerating or decelerating it will be able to
tell you the magnitude of the force and you can time the duration to
find the distance traveled. However, suppose that you are moving at a
constant velocity, the a
You're speaking of OBD or CAN.
There are some good interfaces out there, though the auto companies
try to protect their information. It would be neat to build a
plotter/scanner interface for measuring the car sensors on the Neo
using either bluetooth or serial/usb.

For GeoPointing to work right, you would also need an electronic compass

But guess what: it could be an excellent "excersize" partner, by
