1. A mobile computing device comprising:

  • an accelerometer configured to measure acceleration of at least one axis of the accelerometer;

    communication circuitry configured to wirelessly communicate with other devices;

    a processor; and

    memory storing computer-executable instructions that, when executed by the processor, cause the mobile computing device to;

    receive, from the accelerometer of the mobile device, one or more acceleration measurements measured by the accelerometer of the mobile computing device during a first time window;

    compare the one or more acceleration measurements received from the accelerometer of the mobile computing device to one or more acceleration thresholds;

    based on the comparing the one or more acceleration measurements received from the accelerometer of the mobile computing device to the one or more acceleration thresholds, determine a likelihood that a vehicle associated with the mobile computing device was involved in a crash;

    corroborate, based on one or more sensor measurements different from the one or more acceleration measurements received from the accelerometer of the mobile computing device, the likelihood that the vehicle associated with the mobile computing device was involved in a crash,wherein the one or more sensor measurements different from the one or more acceleration measurements received from the accelerometer of the mobile computing device comprise location data, and wherein corroborating the likelihood that the vehicle associated with the mobile computing device was involved in a crash comprises determining, based on the location data, whether a distance the vehicle traveled during one or more additional time windows after the first time window exceed a threshold distance; and

    based on corroborating the likelihood that the vehicle associated with the mobile computing device was involved in a crash, store data indicative of the likelihood that the vehicle associated with the mobile computing device was involved in a crash.
