Comfort and Convenience
Comfort preferences vary because people sit differently: some want an upright posture with a clear view forward, others settle lower and further back. Neither is correct; it is worth knowing which one you are before you shop.
Safety and Driver Assistance
Learning where wipers, lights, mirrors and hazard switches sit is worth a few unhurried minutes while parked. Searching for an unfamiliar control mid-traffic tends to pull attention from the road at exactly the wrong moment.
Multimedia and Connectivity
Charging is its own need, separate from audio: a phone used for calls and navigation drains steadily on city runs. If a socket or port is available, keeping a cable to hand saves improvising later.
