Reduce the blue large size line a little bit (1/3). It will help the drivers to get the correct small street that is when the avenue ends and turns to 3 small entrances for example:right, left and straigth and they are very close to each other and the blue line hides the gray line. Even with information on top of app, in some moments the internet takes important seconds to update the information and due to this the driver takes the wrong way.
In big cities like São Paulo it will be helpfull during daily routine routes.
Thanks for your time and I hope I can help for app improments.
