On the way to the supermarket via El Camino, someone in a blue Tesla ahead of us put on a display of bad driving. First they wobbled in the lane, so I was looking. Then they signaled right and immediately changed lanes to the left. After they changed lanes again back into the middle, we passed them in the turn lane and the housemate honked to make them aware there was someone in their blind spot. Can't blame that on the autopilot.
