Want to get somewhere, but don't want to miss an email, or risk a break in the directions on the way? A patent granted to Google suggests it's been thinking about the very same thing. Read through the details, and it all sounds fairly familiar -- receiving origin and destination, planning a route etc. But, this time, there's the added hop of accessing wireless coverage data, and stirring that info into the returned directions mix. The flow charts in the literature suggest that this could be a user input option. So, along with the choice of fastest and most economical, maybe some day we'll be seeing one for "fastest data" too. Someone resurrect the term "information superhighway," and quick.
