Comfort and Convenience
Some occupants like a cooler cabin on a long day, while others prefer more warmth once they have been sitting for a while. Those preferences can even differ between the driver and a passenger on the same trip.
Safety and Driver Assistance
A few minutes with lights, wipers, and the horn in a quiet car park means those actions are known before the first junction. A second driver can then take over after lunch without a briefing.
Multimedia and Connectivity
If a charge point is available, a phone holding a booking and a map can stay usable without hunting for a socket. Many people still rely on the handset for the last stretch of directions.
