Comfort and Convenience
Seating position is largely a matter of build and habit: a taller driver often wants more distance from the wheel, while someone shorter may prefer sitting higher for a clearer view forward.
Safety and Driver Assistance
Knowing where the wipers, lights and demister sit is worth a moment in the driveway, because the first rain or tunnel is a poor time to start searching.
Multimedia and Connectivity
A phone that arrives home with charge left is the usual aim on long days; where a powered socket or port is available, it lets navigation and music run without the battery becoming the limiting factor.
