Heh, google is training cars to drive like grandmas.<p>&gt; <i>But the technology, like Google’s car, drives by the book. It leaves what is considered the safe distance between itself and the car ahead. This also happens to be enough space for a car in an adjoining lane to squeeze into, and, Mr. Windsor said, they often tried.</i><p>Yeah. We just don&#x27;t have the infrastructure in major cities for all of us to drive safely. We&#x27;ve been slowly crowding our roads over the last century and we&#x27;re at the point where most people are used to driving with a 1 or 2 second rule. Which isn&#x27;t good, but it&#x27;s how we do things.<p>Now I wonder if google-driven cars would actually be less efficient for LA. Sure there wouldn&#x27;t be any traffic-slowing accidents, but there&#x27;d be 50% less volume traveling 20mph slower.
