Comfort and Convenience
Seating position is a good example: some people want to sit high with a clear view forward, while others prefer a lower, more enclosed feel. Height, leg length and driving habits all pull that preference in different directions.
Safety and Driver Assistance
Spending a little time with the lights, wipers, mirrors and demisting before setting off means less fumbling once you are moving. Preparation of this kind is worth doing in any unfamiliar car, whatever equipment it happens to carry.
Multimedia and Connectivity
Keeping a phone charged through a long day is a practical need in its own right, separate from calls or music. Where a suitable power source is available, the phone can stay topped up while it handles navigation.
