>>1003364 (You)Pic related - it's a random street from my city that could be practically any residential area outside of the central city in any part of the US that was developed before 1950, and it's perfect for cycling without any kind of special adaptation. Traffic is low, the trees discourage speed (unlike modern suburbs that have lots of setback and open sightlines to make things comfortable for drivers), and it's part of a grid (as opposed to a suburb organized around arterial roads).
Cyclists don't need infrastructure - we need neighborhoods that aren't designed for cars at the expense of all other uses.
