Third time is the charm?

BTW, patent 6,175,789 (in-dash computer) is invalidated by the empeg car (http://en.wikipedia.org/wiki/Empeg_Car). Microsoft patented the in-dash computer on September 10, 1999, and the EE Times article (linked on the Wikipedia page) shows Hugo holding a completed Mark I empeg car in May 2, 1999. Since the development had been quite public and going on for years earlier, I would say that at the very least Microsoft's patent is dead by more than four months.
