Comfort and Convenience
Preferred seating position is a clear example: some people like sitting low with arms extended, others upright and closer to the wheel. Height, build and years of habit all shape what feels natural.
Safety and Driver Assistance
It is worth a few minutes before setting off to find where the lights, wipers and demisting controls sit. Sorting that out while stationary means less searching later, particularly at night or in an unfamiliar car.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a need in its own right, separate from taking calls or playing music. Where a suitable outlet or cable is available, the phone can stay topped up en route.
