Comfort and Convenience
Where a driver likes to sit relative to the wheel varies: some prefer arms fairly straight, others closer and more upright. Height, arm length and long-standing habit all feed into that choice.
Safety and Driver Assistance
Before travel it helps to know what the main displays show and where the demister and lighting controls sit, so an unplanned change of weather or a night start needs no learning mid-journey.
Multimedia and Connectivity
Calls on the move are usually wanted hands-free, so a phone that connects once and reconnects automatically afterwards saves fiddling. Whether music arrives the same way, or from a separate source, is a distinct question.
