Actually one thing the watch can do is displaying the turn by turn text, the NEXT turn
For example 2 miles on Main St, RIGHT on Sycamore St
A bit later, 0.5 miles on Main St, RIGHT on Sycamore St
Then do HAPTIC feedback on your wrist to let you know you will turn soon within 0.5 miles
That will be very useful since so then I will not have to glance at my phone for the next turn
Correct. You won't have to glance at your phone. You can now glance at a one inch display whilst removing a hand from the wheel.
