NPR had a story about how self-driving cars in Pittsburgh wouldn't be adhering to the "Pittsburgh-left":
"Even harder for autonomous cars to master are local quirks; things like "the Pittsburgh left." That's a custom unique to the city that allows the first driver trying to make a left turn to do so before oncoming cars pass through an intersection. It's one thing that Emily Duff Bartel says Uber's fleet of self-driving cars won't be programmed to practice. "We're following the rules on this one," she says."
