FIG. 1M illustrates an example vehicle (e.g., autonomous vehicle), comprising a cooling system (e.g., including a deflector), in a side view, corresponding to FIG. 1K and FIG. 1L, according to an embodiment of the present disclosure. FIG. 1M illustrates an example of an operation of the deflector(s) 176 as referenced in FIG. 1K. In FIG. 1M, the deflector(s) 176 may be in an active mode. During the active mode, the deflector(s) 176 may be vertically extended above the groove(s) 178, and above a plane of the vehicle 170 (e.g., a roof of the vehicle 170). For example, during the active mode, the controller may determine that airflow to the enclosure 172 is needed or desired.
