NYT: Wielding Rocks and Knives, Arizonans Attack Self-Driving Cars

In Chandler, AZ, where Waymo is testing their driverless vehicles, "Some people have pelted Waymo vans with rocks... Others have repeatedly tried to run the vehicles off the road. One woman screamed at one of the vans, telling it to get out of her suburban neighborhood. A man pulled up alongside a Waymo vehicle and threatened the employee riding inside with a piece of PVC pipe."
