1. A method for detecting inattentive vehicle operation comprising:
using a camera monitor system (CMS) controller to identify a vehicle centering of a vehicle containing the CMS controller by analyzing at least one image generated by the CMS, the vehicle centering corresponding to how centered the vehicle is within first lane line and a second lane line; and
incrementing an impaired driving counter in response to the vehicle centering deviating from a lane center according to a predefined characteristic;
decrementing the impaired driving counter over time predefined rate to compensate for accidental events; and
based on the impaired driving counter reaching a certain value within a given time period, activating an inattentive driving response.
