Comfort and Convenience
A preferred seating position varies by body height and arm length, so one driver may sit closer to the wheel while another moves the seat farther back for a relaxed reach.
Safety and Driver Assistance
Before setting off, locating the wiper, light, and mirror switches by touch reduces distraction, because controls can shift between different dashboard layouts and steering-column stalks.
Multimedia and Connectivity
If a phone is used for turn-by-turn directions, keeping its screen steady and audible matters more than having the largest display, since route prompts must be understood quickly.
