Comfort and Convenience
Cabin temperature is a personal matter: the same setting feels mild to one person and stuffy to another, depending on clothing and how long they have been outside. Short errands rarely allow a settled compromise.
Safety and Driver Assistance
A minute spent before setting off, finding the lights, wipers and hazard switch, means those functions are already located when they are needed. Learning them while moving competes with the task of driving.
Multimedia and Connectivity
Battery level is the usual concern on an errand day, since navigation and messages drain a phone while it sits in the car. Where a charging facility is available, topping up during short hops keeps the phone usable.
