That's great when the route isn't intentionally confusing like in some cities. "Turn left in 1000 feet" when there is an intersection shaped like an asterisk is one example a ran into recently. I had to stop in the middle of the road (blocking traffic) and dig out my phone so I could see if I should slight left, turn 90 degrees left, or go through and slight left.
I find that the combination of distance updates and street name cover most of those cases, though there are indeed edge-cases where it doesn't work great.
