Zooming the route
Zooming in and out are used to navigate through map areas that are too large or too small to be conveniently displayed within a single window. While following the chevron, zooming alters the map scale because it changes the proportion of the workspace shown in each window.
Sample use case: You are a taxi driver navigating through the city of Łódź, and thanks to the zoom level adjusted to the velocity of your car you see a convenient map area for you to move.
Use the following code snippets to try this in your app:
