1. A system for generating vehicle profiles for detected vehicles based on engine sound recordings, the system comprising:
one or more processors; and
a non-transitory computer-readable storage medium storing instructions, which when executed by the one or more processors cause the one or more processors to perform operations comprising:
receiving a dataset comprising a plurality of engine sound recordings associated with a plurality of vehicles collected by a device external to a corresponding vehicle, and, for each engine sound recording of the plurality of engine sound recordings, (1) a corresponding distance to each vehicle, and (2) a corresponding vehicle model;
training, using (1) the plurality of engine sound recordings, (2) the corresponding distance to each vehicle, and (3) the corresponding vehicle model, a machine learning model to identify vehicle models and distances based on engine sound recording data;
collecting sound data using a microphone external to a vehicle;
inputting, into the machine learning model a range and at least a portion of the sound data to obtain a vehicle model of the vehicle and an indication that the vehicle is within the range; and
in response to receiving, from the machine learning model, the vehicle model and the indication that the vehicle is within the range, generating, based on the vehicle model, a vehicle profile associated with the vehicle.
