Waze often takes us along small roads, not always in good condition, in small villages. This option is disturbing because we don't know where we are going (the intersections no longer indicate our destination). It's dangerous because the roads are not designed for this amount of traffic. It's annoying because it's much more difficult to drive on these small roads with several intersections and turns where the slightest mistake takes us off the right path. And this only saves a few minutes theoretically and they are quickly lost due to the fact that these roads do not allow you to drive fast in complete safety. And what's more, this traffic unnecessarily disturbs the inhabitants of these small roads.
You really need an option to stay on the main roads as much as possible.
