Comfort and Convenience
Comfort begins with seating position. Drivers differ in height, leg length and how upright they prefer to sit, so a setup that suits one person can feel awkward to another.
Safety and Driver Assistance
Locating the wiper, lighting and demister controls while parked means less searching once underway. Preparation of this kind is simply about knowing a car before conditions start asking something of the driver.
Multimedia and Connectivity
Phone use splits into separate needs: keeping the battery topped up, handling calls, and playing audio. Where a system covers all three, each may still depend on its own setting or cable.
