It works the way that if you ask Wahoo ELEMNT app or RideWithGPS to find a route from A to B, the app would suggest riding through the roads/bike paths selected earlier by thousands of cyclist, meaning it's safe. Still cannot find a reason to reinvent the wheel
I had a funny experience on Saturday. I first rode from my place to an excellent cycling store in Warsaw. Then, I asked Wahoo Companion App to find me the best route to see my daughter at another location. The app told me the best way was leading just by the place I lived
