Comfort and Convenience
Comfort preferences are personal: seating position depends on height, leg length and how upright someone prefers to sit. Two people sharing a car rarely settle on the same arrangement, so it is worth sorting out before moving off.
Safety and Driver Assistance
Learning where the basics sit, such as lights, wipers, mirrors and the hazard switch, is best done while parked. Then the first time you need something is not the first time you look for it.
Multimedia and Connectivity
Phone battery is the usual city worry, since short hops with navigation running drain it steadily. If charging is available on board, a cable or holder kept in the car turns that from an occasional problem into a non-issue.
