Thank you all. I've calmed down back to my usual flat line.

Eden is correct. I didn't bother mentioning that the Lexus buzzed me then moved more to the center of the lane. I think the driver wanted me to ride in the dead(door) zone. The street has parallel parking.

I think she was really suprised that I could not only catch up to her but pass her. And that, was a bit of shock value. Her apology seemed genuine.

The sharrow in Hermosa Beach is only few month old. And in LA, its one of very few. So people don't know what to make of it.

In retrospect, I think she was more terrified than me after I tapped her passenger window. For all she knows, I could have been the psycho. So it goes both ways.

As for throwing a rock through the Porche window, that was really bad form. Maybe the two witnesses and the Porche driver will have chaulked it up to a run-in with a psycho cyclist.
