1. A method of motor vehicle detection and identification through audio propagation, the method comprising:
generating source autometric signatures;
broadcasting the autometric signatures;
detecting the autometric signatures;
visualizing the autometric signatures;
determining known autometric signatures;
evaluating and sending autometric signatures to the motor vehicle; and
detecting image similarities of the autometric signatures with deep learning image comparison.
