I'm dubious. A recent trip to the U.S. (SF) felt like utter chaos on the roads and this was reinforced by most cars having at least minor damage. Contrast with Australia where any intersection of even mild traffic (say within a suburb) has a roundabout to control traffic flow, and all decent traffic intersections have lights etc. Speed and red light cameras are everywhere, everyone uses indicators all the time for everything etc. It sounds overbureaucratic but it means that you can drive around and know what each other driver is likely to do. In contrast, the (apparent) unpredictability and what seems like an attitude of almost deliberate rebellion on U.S. roads seems designed for chaos.
