Comfort and Convenience
Seating position is a good example. Tall and short drivers reach the same wheel and pedals from different angles, so the setting one person settles on can feel wrong to the next.
Safety and Driver Assistance
Spending a few minutes stationary with lights, wipers and demisting is simple preparation. Working out where they live before setting off means the first rain shower or dusk is not also a hunt.
Multimedia and Connectivity
Keeping a phone charged on the move is the plainest of these needs, especially when it is also the navigation screen. Where a suitable power outlet is available, a cable long enough to reach a sensible resting spot matters.
