What was the dreaded User Interface that was always being joked about, iDrive ?
Therein lies one of the problems with modern vehicles.... many consumers can't be bothered to program/play with even 10% of the available features in these high-end platforms....
Something like a BMW could well do with something like a Concierge Programming Service.... have a checklist of key programmable features available on a Service Waiting Area pamphlet - and have them programmed during that visit as the customer checks off on the list.
Many people may want to see some of these wizzy features working, few want to wade through the programming steps....
