1. A vehicle exhaust dissipation system comprising:
a fan unit;
one or more processors; and
a memory communicably coupled to the one or more processors and storing a fan control module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to, responsive to a determination that an ambient temperature is equal to or below a fan rotor activation temperature, control operation of the fan unit to generate an airflow directed into an exhaust gas exiting a vehicle from a vehicle exhaust gas opening.
