Comfort and Convenience
Cabin temperature is a common point of disagreement, since passengers sitting still in shade feel cooler than a driver in direct sun. Clothing and personal tolerance add to the gap.
Safety and Driver Assistance
Before setting off in a car you rarely drive, it helps to set the mirrors and locate the hazard switch and gear selector positions, so nothing has to be worked out in traffic.
Multimedia and Connectivity
Listening habits differ: radio needs only reception, whereas playing files from a phone depends on the inputs or wireless options available. Charging is a separate matter, governed by the sockets present.
