Comfort and Convenience
How often to pause for a drink or a stretch is a personal comfort choice. One traveller may stop at each service area, while another prefers to keep going, and neither habit is the rule.
Safety and Driver Assistance
Before a dawn start, it is worth knowing which control clears the screen and which works the washers. Searching for them with gloves on in a dark car park is a poor moment to learn the layout.
Multimedia and Connectivity
A podcast for a quiet stretch of road is a listening need, not a phone call and not a charging task. If the car can play audio, that still leaves power and incoming calls as separate jobs.
