Comfort and Convenience
Seating position is a personal preference: some drivers want to sit high for a clear view of the road ahead, others lower and closer to the wheel. Body proportions and long-standing habits both play a part.
Safety and Driver Assistance
Learning where the basic controls sit, lights, wipers, demisting and the hazard switch, is worth doing while parked. Looking for them later means searching at a moment when attention is already elsewhere.
Multimedia and Connectivity
Phone charging is its own need: a commute that starts with a low battery ends better if power is available on the move. Where a charging point exists, a cable of the right length helps.
