Comfort and Convenience
Comfort preferences differ because people have varying needs for seat firmness or support, so a setting that feels right for one person may not suit another.
Safety and Driver Assistance
Becoming familiar with basic controls before travel saves time and attention later, since locating a switch or dial while driving can distract from the road.
Multimedia and Connectivity
A common phone need is keeping it charged during a trip, which requires a working power source regardless of how calls or music are handled.
