Show slightly more accurate directions.
Sometimes on busy crossroads, especially in the Netherlands, for example, the navigation is a bit lacking. There are two factors here:
1) It doesn't show follow up instructions on screen whenever there is a turn you have to take right away after another turn. In NL it is very common on busy intersections to sort 5 meters after turning into a proper lane, google maps shows this perfectly, but in Waze it doesn't show at all. This causes messy driving sometimes.
2) The arrows on screen telling you which lane to take is in these situations also not always correct. You could have to take the 2nd exit to the right on a busy intersection, 15 meters after the first one, but Waze already shows that you have to take the right lane before the 1st exit, thus making you take a wrong turn. Once again, in NL some crossroads are not straightforward at all, especially when you've never driven in that spot before.
I hope i explained it clearly.
