On the maps app, when on the route planning screen ("from" and "to" with the map showing candidate routes), right of the "from" box there's one of those triple-dot menu buttons. "Route Options" modal lets you check "Avoid toll roads". On web maps, there's also an "OPTIONS" link that expands to show the same stuff. It has some useful features that can go completely undiscovered because they're hidden in screens you wouldn't go on if you're sitting in your car getting ready to drive. Waze has the same options and in my opinion are better presented, since it's much more tailored towards driving navigation. Also, reading this HN thread, I'm glad I'm on a small island with exceedingly well-documented road systems (UK). I think you'd have to be in the northernmost parts of Scotland to really have an issue with dumb route planning here. Had a fun experience when exploring the island of Gran Canaria, where maps wanted us to drive our small rear-wheel-drive rental car down what felt like a 60 degree hill, what was essentially a riverbed with tree roots sticking out of it. Some people on quad bikes had to wait for us to crawl down it with foot constantly on the brakes. Maps had marked it as not even a trail or a small road or whatever but a bonafide 2-lane road!
