5. The method of claim 1 , further comprising generating, based on the set of acceleration data and the set of GPS data, a set of isolated device motion data reflective of relative movement of the user device with respect to the vehicle; wherein the vehicle comprises the GPS receiver; wherein the identity of the driver is determined based further on the set of isolated device motion data.

6. The method of claim 1 , further comprising sampling a set of vehicle identification data during the time period at the user device; wherein the identity of the driver is determined based further on the set of vehicle identification data.

7. The method of claim 6 , wherein:

sampling a set of vehicle identification data comprises sampling, at a microphone of the user device, a set of characteristic vehicle audio data emitted by the vehicle; and

the identity of the driver is determined based further on the set of characteristic vehicle audio data.

8. The method of claim 1 , further comprising determining a relative position of the user device with respect to the vehicle, wherein the identity of the driver is determined based further on the relative position.

9. The method of claim 8 , wherein determining the relative position comprises:

at the user device, sampling a set of beacon signal data; and

determining the relative position based on the set of beacon signal data.

10. A method for driver identification comprising:

movably coupling a user device to a vehicle;

at the user device, determining a state of the vehicle, the state indicative of vehicular travel during a time period;

at the user device, determining a relative position of the user device with respect to the vehicle during the time period;

based on the relative position of the user device with respect to the vehicle, determining a vehicle identifier of the vehicle;

at an accelerometer of the user device, sampling a set of acceleration data during the time period;

at a GPS receiver, sampling a set of GPS data during the time period; and

based on the vehicle identifier and the set of acceleration data and the set of GPS data, determining an identity of a driver operating the vehicle throughout the time period.

11. The method of claim 10 , wherein movably coupling the user device to the vehicle comprises coupling the user device to the vehicle through the driver.

12. The method of claim 10 :

further comprising sampling, at a microphone of the user device, a set of vehicle audio data emitted by the vehicle; and

wherein the vehicle identifier is determined based further on the set of vehicle audio data.

at the user device, sampling a set of beacon signal data; and

determining the relative position based on the set of beacon signal data.

15. The method of claim 14 , further comprising emitting a sonic beacon signal at a sound system of a vehicle; wherein:

sampling the set of beacon signal data comprises sampling a set of sonic data corresponding to the sonic beacon signal using a microphone of the mobile electronic device; and

the relative position is determined based further on the set of sonic data.

16. The method of claim 15 , wherein:

emitting the sonic beacon signal comprises emitting a first sound defining a first frequency and a second sound defining a second frequency, the first and second frequencies substantially similar, the first and second sounds cooperatively defining a phase offset; and

determining the relative position comprises:

determining a sonic interference characteristic based on the set of sonic data; and

determining the relative position based on the sonic interference characteristic, the first frequency, and the second frequency.

17. The method of claim 10 :

further comprising sampling, at a microphone of the user device, a set of characteristic vehicle audio data emitted by the vehicle; and

wherein the vehicle identifier is determined based further on the set of characteristic vehicle audio data.
