If you're navigating with a watch on, it'll notify you of upcoming turns (either through vibrations or by making a turn signal-like noise) without ducking/pausing your music.
And, the taps on your wrist are unique depending on which direction you need to turn, so you can theoretically navigate via the wrist-taps alone.
This is wonderful for when you're on a motorcycle going somewhere new. Absolute game changer!
Uses different haptics for left and right turns as well.
No I am not. The Watch taps my wrist as I drive with different patterns for left or right. If I can't tell which it's indicating, I can quickly look at my infotainment screen and see the map. But I am not driving while looking at my Watch, no. That would be very dangerous.
