Comfort and Convenience
Some passengers want air blowing directly at them; others dislike a draught and prefer it aimed at the windscreen or floor. Height, build and habit all feed into that, which is why travelling companions rarely agree.
Safety and Driver Assistance
Before setting off, it pays to know how the mirrors, hazard warning switch and parking brake are operated. Doing that in a quiet moment means fewer decisions later, when attention belongs on the road ahead.
Multimedia and Connectivity
Taking a call on the move is mainly a question of hands-free operation. If the system supports it, pairing the phone before departure is easier than attempting it later, and it keeps the conversation off a handheld device.
