Part of it was probably my fault by relying on the sensors too much. The tire dealer showed me the failed tire and pointed out that right where it blew apart, the tread was quite warn off on one side. He said that this is evidence that the cords were broken for a while (don't know just how long). I guess the thing to do is inspect the tires often and question ANY strange wear patterns or bumps - sidewall and tread!
