“The car’s task is to stay centered between the stripes. Generally, it does a good job of this. Too good, at times—such as when passing a giant semi that’s riding the lane stripe. The car’s radar senses the semi, and the car draws a conclusion along the line of: “There’s something big to my right, but I’ve got seven inches of clearance, so I’m OK.” Meanwhile, the human driver is freaking out.”
