If you honk at a Waymo, doesn’t hear you?

I was in the right lane of a two lane street in pretty heavy traffic today. The right lane was more open, while the left lane was completely backed up and stopped.

A Waymo behind me decided it needed to change into the left lane, presumably because it has a left turn coming up. The problem was, it angled itself across the right lane and then… stopped to wait with its blinker on.

As I drove away from it, I felt bad for all the cars stuck behind the Waymo. If any other idiot blocked an entire lane of traffic because they didn’t merge over sooner, they’d get honked at (along with a few arm gestures to gtfo of the way probably!)

If you honk at a Waymo, does it hear?
