Comfort and Convenience
Preferred seating posture is a good example: some drivers like sitting upright and close to the wheel, others further back and more reclined. Height, arm length and years of habit all pull the preference in different directions.
Safety and Driver Assistance
Spending a few minutes with wipers, lights, mirrors and demisting before setting off means those controls are found by memory later, rather than searched for at the moment weather or traffic suddenly demands them.
Multimedia and Connectivity
Battery level matters on an errand day, since navigation drains a phone quickly. Where a charging point is available, keeping a suitable cable in the car turns topping up into a routine rather than an emergency.
