Comfort and Convenience
Cabin temperature is the clearest example of a preference that resists agreement. Height, clothing and simple habit mean two people sharing the same seat row often want different settings, which is why the topic reappears on every shared journey.
Safety and Driver Assistance
A short pause before setting off pays for itself. Locating hazard lights, demisting and the horn while parked means they are not being searched for later, and the search is what preparation is meant to remove.
Multimedia and Connectivity
Keeping a phone charged is the plainest of everyday needs. A journey that begins with a low battery ends with navigation, tickets or messages in doubt, so if power is available on board, it is worth using from the start.
