The method includes providing, by the query device, a request to the at least one target device to cause the at least one target device to retrieve the selected data stored locally at the target device. The method includes receiving the selected data from the target device. The method includes providing the selected data as an electronic output.

provide a request to the at least one target device to cause the at least one target device to retrieve the selected data stored locally at the target device, including instructions to communicate instructions that cause the target device to search stored data for the selected data, and, in response to identifying the selected data, transmit the selected data without additional data from the stored data;
receive the selected data from the target device that is a remote vehicle; and
provide the selected data as an electronic output to adapt functioning of the remote vehicle according to driving behaviors derived from the selected data.
2. The query system of claim 1 , wherein the instructions to identify the at least one target device include instructions to query metadata stored in the index describing the vehicle data stored by the distributed devices without querying the vehicle data directly, and
wherein the vehicle data includes sensor data and telematics data of reporting vehicles described by the metadata, the sensor data including at least images.
3. The query system of claim 1 , wherein the instructions to identify the target device include instructions to query the index for information selected from a group including a vehicle behavior, a geographic location, a time, content of sensor data, and a vehicle state indicating a scenario associated with a combination of objects, locations of the objects, and a roadway context.
4. The query system of claim 1 , wherein the query specifies contents of the selected data and attributes of the selected data including a quality of sensor data depicting the contents.
5. The query system of claim 1 , wherein the instructions to receive the selected data from the target device include instructions to receive a segment of stored data from the target device that is extracted from the stored data according to characteristics from the query indicating metadata about the selected data.
6. The query system of claim 1 , wherein the instructions to provide the selected data include instructions to adapt the functioning of the remote vehicle by performing one or more of adapting navigation of a location associated with the selected data by altering a trajectory of the remote vehicle and re-routing the remote vehicle at the location.
7. The query system of claim 1 , wherein the index includes derived data that characterizes stored data of the distributed devices, including content of sensor data and relationships between objects depicted in the sensor data with one of the distributed devices that captured the sensor data, and
wherein the index organizes the stored data of the distributed devices by at least a geographic location of where the sensor data was acquired and a time of when the sensor data was acquired.
8. The query system of claim 1 , wherein the distributed devices are one or more of vehicles and edge devices.
9. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
responsive to receiving a query for selected data stored among one or more distributed devices, identify at least one target device of the distributed devices that matches the selected data using an index of vehicle data stored on the distributed devices;
provide a request to the at least one target device to cause the at least one target device to retrieve the selected data stored locally at the target device, including instructions to communicate instructions that cause the target device to search stored data for the selected data, and, in response to identifying the selected data, transmit the selected data without additional data from the stored data;
receive the selected data from the target device that is a remote vehicle; and
provide the selected data as an electronic output to adapt functioning of the remote vehicle according to driving behaviors derived from the selected data.
10. The non-transitory computer-readable medium of claim 9 , wherein the instructions to identify the at least one target device include instructions to query metadata stored in the index describing the vehicle data stored by the distributed devices without querying the vehicle data directly, and
wherein the vehicle data includes sensor data and telematics data of reporting vehicles described by the metadata, the sensor data including at least images.
11. The non-transitory computer-readable medium of claim 9 , wherein the instructions to identify the target device include instructions to query the index for information selected from a group including a vehicle behavior, a geographic location, a time, content of sensor data, and a vehicle state indicating a scenario associated with a combination of objects, locations of the objects, and a roadway context.
12. The non-transitory computer-readable medium of claim 9 , wherein the query specifies contents of the selected data and attributes of the selected data including a quality of sensor data depicting the contents.
13. The non-transitory computer-readable medium of claim 9 , wherein the instructions to receive the selected data from the target device include instructions to receive a segment of stored data from the target device that is extracted from the stored data according to characteristics from the query indicating metadata about the selected data.
14. A method, comprising:
responsive to receiving a query for selected data stored among one or more distributed devices, identifying, by a query device, at least one target device of the distributed devices that matches the selected data using an index of vehicle data stored on the distributed devices;
providing, by the query device, a request to the at least one target device to cause the at least one target device to retrieve the selected data stored locally at the target device, including communicating instructions that cause the target device to search stored data for the selected data, and, in response to identifying the selected data, transmitting the selected data without additional data from the stored data;
