Comfort and Convenience
Preferred seating height is a common example: some drivers like sitting high for a broad view of the road, others prefer a lower position. Body proportions and habits built over years explain much of that difference.
Safety and Driver Assistance
Spending a few minutes with wipers, lights, mirrors and climate settings while parked means fewer unfamiliar movements later. Preparation of this kind is simply part of settling into any car that is new to you.
Multimedia and Connectivity
Keeping a phone charged on longer trips matters to many people, and it is a separate question from how calls are handled or how music reaches the speakers. Check which options suit your routine.
