I've thought of another. There's a bit on my commute where I turn right off the road to get to a shared path. So, I'm near the centre line, I can see the gap between cars about four cars back, and I'm waiting for the traffic to pass so I can nip across in that gap.
Hang on, the front car is slowing down. They've stopped. They think they're doing me a favour and want me to go in front of their vehicle when there may be a idiot cyclist flying up their left hand side. No thanks, I'll wait. Now it's my fault, I've held them up and they drive off in a snot. All the people behind them have also had to slow down so they don't like me either and the gap has disappeared.
