Comfort and Convenience
Cabin temperature is the classic point of disagreement: what one person calls pleasant, another finds stuffy or draughty. Preferences differ with clothing, seating position and simply how warm someone tends to feel.
Safety and Driver Assistance
A few minutes spent locating lights, wipers, the hazard switch and mirror adjustment before setting off is time well used. Sorting this while stationary means there is nothing left to work out once passengers and traffic demand attention.
Multimedia and Connectivity
Passengers often board with a nearly flat phone, so keeping it charged during the trip is the practical concern. Where a suitable power outlet or cable is available, navigation and messaging can continue without rationing battery.
