This option would greatly help in cases where there are many nearby streets and avenues, and bridges above these streets and avenues, not allowing us to see clearly the way we should go, or if we must keep at right or left on the track.

For example this screenshot:

...and it gets worse when we are viewing in 3D mode (looks like a big yellow block), as the example of the same avenue:

A smaller thickness for the avenues and streets could look like this examples (edited images):

The screenshots were taken in Brazil's map, São Paulo city, at the coordinates: -23.515856,-46.727073.

Of course this option, to reduce the thickness of the streets, would be optional, because in many countries most of the avenues and streets are planned and are far enough from each other, preventing that this kind of confusion occurs during navigation, but for countries where the streets and avenues are poorly planned, this option would be very useful.

Could be something simple, an option called "Thickness Size", with values ​​ranging from: 5 (the current and default size used in waze), 4, 3, 2 and 1, this last being the lowest possible value for thickness size.

Thanks in advance.
