> For example, UPS drivers are generally prohibited from making left turns because it's considered less efficient to do so. No, they aren’t “generally prohibited from making left turns” - that’s a misrepresentation. The truth is that their routing-engine is optimised for reducing idle time waiting at lights which meant that _consequently_ their navigation+routing instructions given to the driver will avoid left-turns. That’s all it is. (When the media references this they make it sound like eliminating left-turns is the objective, rather than the end-result)
