I love using waze but one thing that always annoys me, especially when in areas I am not familiar with, is not knowing what the next direction is until I've completed the first.
For example, when exiting a highway there is no indication of if you should be turning left or right at the on-ramp until you have gotten close to the end of the ramp. I would find it really helpful if in scenarios like this the directions read "take exit ramp on right and then get in far left lane to take a left" or something similar to that.
