Comfort and Convenience
Cabin temperature is a common point of disagreement. Passengers differ in what counts as warm, so a setting that suits the driver can feel wrong beside them. Clothing and seat position add to the difference.
Safety and Driver Assistance
Control layouts vary between cars, so a habit formed in one model does not always transfer. Working through the indicator stalk, light switch and demister while stationary makes their positions easier to recall.
Multimedia and Connectivity
Keeping a phone charged on a long drive is a different matter from playing audio through the car. Where a socket or charging pad is provided, its position decides how easily it is reached.
