1. An intoxication detection system of a vehicle, comprising:
a passive breath sensor configured to measure an amount of an intoxicant present within a passenger cabin of the vehicle;
a camera configured to capture images including a driver on a driver's seat within the passenger cabin of the vehicle;
a radar sensor configured to output radar signals toward the driver's seat and receive signals reflected back to the radar sensor;
a baseline module configured to determine baseline parameters for the driver based on images from the camera and the signals received by the radar sensor; and
an intoxication indication module configured to output an indicator that the driver is intoxicated when both (a) the amount of the intoxicant is greater than or equal to a predetermined amount of the intoxicant and (b) at least one present parameter of the driver is different than a respective one of the baseline parameters for the driver by at least a predetermined amount.
