I’m betting that Phone As A Key will be one of those features that many wonder what took so long; but as others have said you’re not forced to use it; you still have a conventional fob, so I don’t understand the backlash towards giving people options—of course it’s not a necessity, but that’s what luxury is all about. I’ve already come to the conclusion this is my next car, now I just have to decide on colors—definitely want the Take Flight theme, though.
