1. A method for attributing vehicle telematics data to individuals, the method comprising: receiving, at a server, vehicle telematics data collected by a data collection device during a plurality of trips, wherein the vehicle telematics data includes a plurality of subsets of vehicle telematics data each corresponding to a different one of the plurality of trips; for each subset of the plurality of subsets of vehicle telematics data, using the subset of vehicle telematics data to generate a respective one of a plurality of metric sets, wherein each of the plurality of metric sets includes a plurality of metrics each indicative of a different driving behavior or a different feature of a driving environment; retrieving, by the server and from a policy database, policy information pertaining to an insurance policy associated with the data collection device; determining, by the server and based upon the retrieved policy information, a number N of disclosed drivers associated with the insurance policy, N being greater than or equal to zero; performing, by the server, a statistical analysis on the plurality of metric sets at least by executing a k-means clustering algorithm on the plurality of metric sets, wherein executing the k-means clustering algorithm includes (i) setting k equal to N, and (ii) generating indications of which of the plurality of metric sets belong to which of k clusters, each of the k clusters corresponding to a different one of the N drivers; for each metric set of at least some of the plurality of metric sets, and based upon the generated indications, assigning, by the server, one or both of (i) the metric set, and (ii) the corresponding one of the plurality of subsets of vehicle telematics data, to one of the N disclosed drivers; and causing, by the server, an insurance rating associated with the insurance policy to be adjusted based at least in part on (i) the vehicle telematics data and (ii) the manner in which the corresponding ones of the plurality of metric sets or the plurality of subsets of vehicle telematics data are assigned to the N disclosed drivers.
