Comfort and Convenience
Preferred seating position varies with height, build and driving habits, so a setup that suits one person can feel wrong to another. Drivers who share a car tend to reset theirs before setting off.
Safety and Driver Assistance
Spending a minute on lights, wipers and mirror angles before moving means those actions later come from memory rather than searching. An unfamiliar car especially rewards a short look around the cabin first.
Multimedia and Connectivity
Charging, calls and music are separate needs. A cable may replenish the battery without carrying audio, while a wireless link might handle music or calls but leave charging to something else entirely.
