Please don't let one idiot ruin it for you! One time I was wanting to turn at an intersetion but it was a busy'ish road and I slowed, pulled over, checked behind and then pulled into the centre and signalled my turn. It took some time to do all this. In the meantime a car that was on a STOP sign, pulled out in front of me (they were probably unclear what my intentions were) and stopped in the middle of the road, leaned over to wind down the opposite window and yelled at me. Again, they were on a STOP sign but no, I was the problem!
Did I stop biking forever after? No, I recognised that they were an idiot that massively over reacted to a simple misunderstanding and put everyone at risk to have a tantrum in the middle of the road!
