One thing you'll notice if you look at a lot of suburban sprawl in the US is that most of the roads are wide and have sidewalks, but the houses are ugly and samey for miles. Interspersed among those neighborhoods will be roads with smaller--or at least older--houses, and smaller streets. The reason being that those smaller streets are from the neighborhoods that existed before the area was built up and the locals resisted development in their neighborhoods. McKinney is a town that has apparently undergone rapid expansion in the past 20-30 years and I'm willing to bet that Pine St was initially build well before McKinney reached its current population. If you believe that every single residential road needs to have a certain width and have sidewalks as a matter of course, I don't know that I can dissuade you, but I'm willing to bet that the residents on that road are not eager to give up a portion of their yards for a wider road and sidewalk and they almost certainly would rather that road not receive more traffic as a result of 'improvement'. That said, there are definitely roads in Townsville Qld (your example of an Australian town that should have good infrastructure,) that look as 'bad' if not worse than Pine St: https://www.google.com/maps/@-19.3152528,146.8315158,3a,75y,316.97h,83.1t/data=!3m7!1e1!3m5!1s3GCaMvUdz4i2LNa-cRkydw!2e0!6s%2F%2Fgeo3.ggpht.com%2Fcbk%3Fpanoid%3D3GCaMvUdz4i2LNa-cRkydw%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D231.79164%26pitch%3D0%26thumbfov%3D100!7i3328!8i1664 https://www.google.com/maps/@-19.3152528,146.8315158,3a,75y,...
