That'd be interesting. Do anyone know the precision of the 
accelerometers? Assuming, of course, that one has a car mount so the 
phone has a known orientation relative to the car. How long tunnels 
would be feasible? Where I live, there are some 4km tunnels that curve 
slightly, and a shorter one with a roundabout inside. :-/

Usually, one also uses the car speedometer for this. I have a box that 
converts this to serial - perhaps a serial to usb converter could be 
used to connect the phone.
