This article is so auto-centric, the author only considers the safety of people inside cars. Banning left turns in cities is a GREAT idea! The group of people most threatened by left turning cars are people walking. Control F for "pedestrian" or "walk" in this article. Nothing. American traffic engineering is so car-dominant, they fail to consider the most vulnerable road users. Pedestrian fatalities in the USA are at 30 year highs. Design for the healthy human living habitat we desperately need. Good human habitat requires safe walking infrastructure for humans of all ages, sizes & abilities.
