Comfort and Convenience
Cabin temperature is a common point of disagreement on a long drive. Preferences depend on clothing, where someone sits relative to the sun, and simple habit, so what suits the driver may not suit a rear passenger.
Safety and Driver Assistance
A few minutes stationary before setting off is enough to locate hazard lights, demisting and the horn. Doing that in a calm moment means the first attempt is not made in traffic or poor weather.
Multimedia and Connectivity
Battery level matters most on a long day, since navigation and messaging drain a phone steadily. Where a charging point is available in the cabin, it lets the device top up during the drive rather than overnight.
