I had similar problem few days ago. No threat for life but serious threat for my car - the route suggested was full of very deep holes.
I've just tried to suggest a change, but as it happens often with Google documentation - the description of what to click matches nothing (there's no menu item labelled with the phrase from documentation - I use Polish version).

Edit: found it, but docs are misleading.
