Comfort and Convenience
Seating position is personal: height, reach and posture habits differ, so one person's ideal setup feels wrong to the next. Two drivers sharing a car usually settle on different compromises between visibility and arm comfort.
Safety and Driver Assistance
It is worth spending a few stationary minutes learning where the essentials are: lights, wipers, demist, hazard switch. Preparation done in a parked car is preparation not improvised in moving traffic.
Multimedia and Connectivity
Navigation on a phone drains the battery quickly, so a charging point matters on longer errand chains. Where charging is available, the question is simply whether the cable reaches a spot the driver can glance at.
