Comfort and Convenience
Where a driver likes to sit varies with height, build and habit; some want a high, upright view, others a lower, more reclined setting. That is why the same position rarely suits two people equally.
Safety and Driver Assistance
Wipers, lights and demisting are needed at short notice, often in the middle of traffic. Locating them while stationary, before setting off, means one less thing to search for when the road asks for attention.
Multimedia and Connectivity
Short city trips rarely leave much time to charge a phone, so a battery that starts low often ends low. Where a power outlet is available and reachable, topping up during the drive is the practical use.
