The Dutch know how to build bike infrastructure like nobody else. Their network of bikeways is made up of 3 main street typologies. One is quiet, low-speed (<20mph) residential streets that offer through access to bikes and pedestrians, but not to cars (known as bike boulevards or neighborhood greenways in the US). The second is physically separated bike lanes that parallel higher speed motorized thoroughfares, and have priority at intersections. The third is fully separated bike paths, which are not shared with pedestrians or strollers or pogostick riders, and which are wide enough for two riders side-by-side in each direction. Getting this stuff built in the US is a political issue, not a technical one.
