Comfort and Convenience
Seating position is personal: height, leg length and the way someone likes to hold the wheel all pull in different directions. Two people sharing one car often want noticeably different settings for the same journey.
Safety and Driver Assistance
It is worth spending a moment before setting off to locate wipers, lights and demisting. Preparation belongs in the parking space rather than mid-junction, where hunting for an unfamiliar control competes with everything else demanding attention.
Multimedia and Connectivity
Phone charging is its own question, separate from calls or music: a commute long enough to matter usually ends with less battery than it began. Where a charging point is provided, using it quickly becomes routine.
