Comfort and Convenience
Seating position is personal: height, reach and posture differ, so a setting that suits one driver feels wrong to the next. In shared cars, this is why people readjust before setting off.
Safety and Driver Assistance
Locating lights, wipers, demisting and hazard switches before moving means not searching for them later. A minute spent while parked keeps a driver's later decisions about the road rather than the dashboard.
Multimedia and Connectivity
Battery level is the usual city worry, since navigation drains a phone across a morning of short trips. Where in-car charging is available, it keeps the device usable for the rest of the day.
