Comfort and Convenience
Cabin temperature at school pickup differs between people. Some like cooler air on a warm afternoon, others want the cabin warmer on a cold morning, and habit plus weather explain the difference.
Safety and Driver Assistance
Locating lights, wipers, and the demister on a foggy morning before leaving is useful preparation. Those steps are then already known when the journey begins.
Multimedia and Connectivity
An everyday phone need is taking a short call while parked at a clinic. If call audio can be heard in the cabin, the conversation need not stay on the handset; music playback is a separate choice and charging is another.
