Comfort and Convenience
Comfort preferences vary with height, build and habit. A tall driver and a short one rarely agree on where a seat should sit or how upright a backrest should be, so one settled position can feel wrong to someone else.
Safety and Driver Assistance
Learning where the basic controls sit is worth a few minutes before setting off, particularly in an unfamiliar car. Lights, wipers and demisting are needed at short notice, and a stationary vehicle is the calm place to find them.
Multimedia and Connectivity
A phone used for navigation loses charge quickly, so keeping it powered is a separate need from playing music or taking calls. Where a car supports these, each may rely on a different connection.
