Comfort and Convenience
Some people want everything within arm's reach, bottle, phone, keys, while others prefer a clear, empty cabin. The difference comes from habit and from how many stops a typical day involves, not from any rule.
Safety and Driver Assistance
Familiarity works best when it is deliberate: sitting still, adjusting mirrors, checking how the gear selector and parking brake behave. Unfamiliar cars reward that minute, especially before a first drive in traffic.
Multimedia and Connectivity
Calls arrive mid-errand, and answering while driving is only sensible hands-free. Where a car offers hands-free calling, setting the phone up once beforehand avoids fiddling at the kerb; music and charging remain separate concerns.
