Agreed that the recreational biking infrastructure in NW Arkansas is great, but not enough Fayetteville people bike for transportation for that to be a big part of this outcome. It's just 1% of all commutes, for example. Compare that to 4%-10% in university towns that use a lot of on-street bike lanes that take you more directly to destinations: Eugene, Corvallis, Bozeman, Madison, Fort Collins, Palo Alto, Berkeley, Ann Arbor. (Not saying those cities are perfect either, to be clear.)

It's true that shitty bike lanes on auto-oriented streets are shitty, and that off-street paths are great. But lanes and paths are not the same thing, and neither of them is the reason this policy is working in Fayetteville.
