Got honked at yesterday while riding in the centre of the left lane on a two-lane road (preparing for a left turn) with the right lane blocked by some right-turners. The honk was short, and I just made the left turn signal in response, which seemed to have stopped any further noise making from the driver. Pretty civilized, actually, I think: for a change I feel good about how I handled a honk (hey, no finger! and my blood didn't even boil ).
