1. A method comprising:

detecting by a sensor in a vehicle a movement of a first object in the vehicle when the vehicle is in motion;

monitoring input from one or more processors related to one or more systems associated with maneuvering the vehicle, wherein the one or more systems comprise a braking system of the vehicle, a turning system of the vehicle, or another system related to the maneuvering of the vehicle;

determining that the maneuvering of the vehicle exceeds a threshold level based on the input;

in response to the determining that the maneuvering of the vehicle exceeds the threshold level, analyzing the movement of the first object, wherein the analyzing comprises:

detecting a frequency of movement of the first object,

determining that the first object is an inanimate object based on the frequency of movement exceeding a threshold value frequency, and

assigning the movement of the first object as a benchmark for the movement of an inanimate object;

detecting a frequency of movement of a second object in the vehicle;

comparing the frequency of movement of the second object to the benchmark established using the frequency of movement of the first object; and

determining that the second object is an inanimate object based on the comparing to the benchmark.
