Comfort and Convenience
Seating position is the clearest example: height, reach to the wheel and how upright someone chooses to sit are matters of build and habit. Two people sharing one car often settle on noticeably different arrangements.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit before setting off is simple preparation. Done while parked, it means the first unfamiliar moment on the road is not also a search for a control.
Multimedia and Connectivity
A frequent need is arriving with a charged phone after a long day out. Charging is a separate matter from hands-free calling or playing audio, and where such functions exist each is used in its own way.
