Comfort and Convenience
Cabin temperature divides travellers more than most things: what one person calls pleasantly warm, another finds stuffy, which is why agreement on the setting is often negotiated early in a shared journey.
Safety and Driver Assistance
A few minutes stationary, spent adjusting mirrors and trying the indicator and hazard switches, removes guesswork later. The point is preparation: unfamiliar layouts are easier to learn parked than in moving traffic.
Multimedia and Connectivity
Calls on the move are a common need, and hands-free operation through the car's audio keeps a conversation audible; where such a function is present, pairing it before departure saves fiddling later.
