A big road having bike lanes is perfectly fine. Moreover it's encouraging to see people talking of putting bike lanes for commuters. But that's a bikeable area, not a walkable one. And these 2 make sense in diff situations.

As long as kids and old people are able to walk or slow cycle most places, unsupervised (in a 20-40 minute radius around their homes), I'm happy with that. A place suitable for these 2 demographics is walkable for almost everyone else as well.
