Comfort and Convenience
On a short shop run in outdoor clothes, some people prefer a cooler cabin so they do not feel overdressed, while others want more warmth because they feel cold once seated. Those preferences are personal rather than universal.
Safety and Driver Assistance
Before collecting guests from a station, it helps to know how the hazard switch and window controls work, so those actions are not a scramble on the forecourt. The point is knowing those controls in advance.
Multimedia and Connectivity
A passenger on a quiet errand may want a podcast rather than a phone call or a charge. If cabin audio playback is available, that listening can continue through the trip without involving the driver's handset.
