Comfort and Convenience
Cabin temperature is one of the clearest examples of personal preference. Two people making the same short trip can disagree on it, because clothing, how recently they were walking outdoors and simple habit all differ.
Safety and Driver Assistance
Time spent before setting off, adjusting mirrors and locating the gear selector, hazard switch and parking brake, is rarely wasted. Urban driving offers few quiet gaps in which to work something out from scratch.
Multimedia and Connectivity
Calls are the part of phone use that city traffic complicates most. If hands-free calling is set up and working, a conversation can be handled without the handset, which is what most drivers actually want.
