TomTom loses the Tweeting plot

Is it just me, or does anyone else just want their satnav to tell them how to get between points A and B (possibly via C) as quickly as possible? I ask as I have a press release here that assures me TomTom is introducing a new feature that will satisfy that greatest of needs of the average motorist: the ability to automatically tell everyone on Twitter not only where you are going but when you are likely to arrive there.
