Comfort and Convenience
Seating position is a personal preference: some drivers sit upright and close to the wheel, others further back with arms extended. Neither is correct, since body proportions and habits differ from one person to the next.
Safety and Driver Assistance
Learning where the wipers, lights, mirrors and hazard switch sit is worth doing while parked. Preparation of that kind means fewer moments spent searching for a control once traffic demands attention.
Multimedia and Connectivity
Battery level matters on days full of short trips, so a charging option, if available, keeps a phone usable. Charging is separate from calls and from audio playback, which rely on their own arrangements.
