Comfort and Convenience
Seating position is the clearest example: some drivers want to sit high for a long view down the road, others low and close to the wheel. Build, leg length and habit all pull in different directions.
Safety and Driver Assistance
Spending a few minutes before setting off to locate lights, wipers and mirrors is simple preparation. Doing it while parked means nothing has to be worked out for the first time in moving traffic.
Multimedia and Connectivity
Charging is the plainest need: a phone used for navigation drains quickly over a week of trips, so where a power source sits and whether a cable reaches it shapes the daily routine.
