Comfort and Convenience
Cabin temperature divides households. One person is comfortable at a setting another finds chilly, and factors such as clothing, time of day and how recently someone came in from outside all shift the preference.
Safety and Driver Assistance
Preparation is largely about sequencing. Adjusting mirrors, seat and route while still parked keeps those tasks out of the moving part of the journey, which is the practical argument for an unhurried start.
Multimedia and Connectivity
Hands-free calling addresses a narrow but common need: taking a call without holding a handset. Where such a function is available, setting it up once at home is easier than attempting the setup in traffic.
