Comfort and Convenience
Comfort preferences differ mainly because bodies do: height, leg length and back shape all change where a driver wants support. A seating position that suits one person can feel wrong to another.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit is easier while parked than in moving traffic. Familiarity means fewer moments spent searching for a control when attention is needed elsewhere.
Multimedia and Connectivity
Charging a phone and streaming music are separate needs, and hands-free calling is another; where wireless audio is available, it carries sound but leaves charging to a cable or pad.
