Japanese SatNav devices are being updated with information on where cars have been broken into or stolen and then doling out advice on where to park…
I like the idea that the SatNav voice could tell you more about the area, perhaps offer some tips on your destination on the way. You might need to let the SatNav know more about you, so it can offer advice on what bars in the area to avoid “You won't like the music in there” .
