Comfort and Convenience
Cabin temperature is a personal matter. One occupant is content a couple of degrees cooler than the next, and that gap is most obvious on a short errand, before anyone has properly settled in.
Safety and Driver Assistance
A moment spent locating the hazard switch, mirrors and demisting before pulling away is time well used, especially in a car that is new to the driver. Preparation of that kind costs almost nothing.
Multimedia and Connectivity
Phone battery is the recurring errand concern, since maps and messages drain it between stops. Where a charging option is present, topping up on short hops keeps the phone usable for the next task.
