Since WWII, the majority of US infrastructure has been built around cars. The result is that even low density areas end up with 10+ lane streets and monstrous size intersections like the one pictured below.
Not a big deal if you just drive around everywhere. But it sucks for people who want to walk. It turns pedestrian trips into a labyrinthine and dangerous affair.
Wide car lanes are sometimes necessary. They're useful in the form of highways or for main streets that cut through high density areas. But even this is probably a sign of poor urban planning.
Don't these streets look safer for walking? 1-2 car lanes. No on street parking. Streets like this invite people to walk or bicycle. For longer distance travel, people can take the bus or train.
American streets are too damn wide. Right?!
