And I got honked at when I slowed down to make my left turn. And yes, I had bike lights on, and I was signaling my turn. Didn't even have to come to a complete stop to make said turn.
So general conclusion: Screw you, population of Palo Alto. Clearly, I, as a biker, am not wanted anywhere. Therefore, I'll stick with the optimal, safer route for me, regardless of whether it's sidewalk or road. You'll have to deal with it.
