(writing on phone so apologies for bad grammar etc) Riding home, am in right hand line behind (and perhaps foolishly on the left of the lane) a van that's waiting to go right, while i'm waiting to in straight on. A car pulls up behind me and starts creeping forwards to go beside me. I turn and look, gesturing to back off a bit as i'm worried they are going straight on which as the road turns back to one lane would be dangerous for me. The van ahead then gets an opportunity to turn and does, and the car revs it's engine. Thinking this is aggression to me i for some reason find myself flipping the bird at them, which i immediately feel stupid for doing. The driver then turns right which i wasn't expecting, and his passenger shouts knob head at me. I think i might have just made another person hate cyclists for no reason Sorry to them, and sorry to all cyclists! I still have a lot to learn...
