Comfort and Convenience
Drivers differ in how high they like to sit. Some prefer a raised view along the bonnet, others a lower and more enclosed position, so the same cabin can feel quite different to two people.
Safety and Driver Assistance
Spending a few quiet minutes with wipers, lights and mirrors while parked means fewer unfamiliar movements later. Preparation here is simply knowing which control does what before traffic starts competing for attention.
Multimedia and Connectivity
A phone that runs flat mid-journey is a practical nuisance, so charging deserves its own thought. Calls and music are separate questions again, each depending on what a particular setup happens to support.
