Go for a walk where? On the side of the stroad? With your friends who live 10Km away and have to drive to meet you because there's no public transport?
My take is that Americans like to make infrastructure an excuse for everything when it really boils down to priorities and preferences.
10 km is a 20 minute bike ride if you're not too obese to fit on one. 10 minutes if you pick a coffee shop, pup, or Park that is halfway. Unfortunately, most people prefer Netflix and the fridge which is even closer
