Comfort and Convenience
Comfort preferences vary because people differ in height, build and driving posture; a seating position that suits one driver can leave another reaching or sitting too upright. Most find their own compromise over time.
Safety and Driver Assistance
Learning where the basic controls sit, such as lights, wipers, demisting and the hazard switch, before setting off means less searching later, when attention is better spent on the road.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a common need; where a suitable cable or pad is available, charging continues independently of whether audio or calls are routed through the car.
