1. A method comprising:
receiving, by a driver drowsiness detection system, a first motor cortex signal of a plurality of motor cortex signals from a brain activity monitoring element attached to a driver of a vehicle;
identifying, by the driver drowsiness detection system and based on the first motor cortex signal, anatomical parts of the driver that are associated with a brain activity, wherein the anatomical parts of the driver comprise an eye, a face, a limb, and a torso;
determining, by the driver drowsiness detection system, a drowsiness state of the driver by evaluating physical activity of the anatomical parts and weighting each of the plurality of motor cortex signals; and
assigning, by the driver drowsiness detection system and based on the drowsiness state of the driver, a first sleep risk score.
