Comfort and Convenience
Seating position is personal. Height, leg length and posture habits vary, so two people rarely find the same position natural, and what feels well supported to one driver can feel too upright to another.
Safety and Driver Assistance
Spending a couple of minutes with the lights, wipers, mirrors and heating before pulling away means less hunting for them later. Preparation is simplest while parked, when nothing else is competing for attention.
Multimedia and Connectivity
A long drive drains a phone battery, especially with the screen on for navigation. Where a car provides a charging point within reach of the front seats, the phone stays usable for the whole route.
