Comfort and Convenience
Where a driver likes to sit relative to the wheel is personal: height, leg length and the habit of resting an arm all shape what feels natural, so one settled position rarely suits two people.
Safety and Driver Assistance
Spending a few minutes with wipers, lights, mirrors and the hazard switch while parked means those actions later come from memory rather than searching, which helps keep attention on the road instead of on the dashboard.
Multimedia and Connectivity
Keeping a phone charged during a long day matters when it also carries navigation; if a charging point is available, a cable routed to a stable spot avoids the handset sliding about while a route runs.
