Was out minding my own business on my bike yesterday when some nutcase in a car behind me sounded his horn, zoomed past with his wing mirror centimetres from my handlebars, slowed down right in front of me and started yelling out of the window that I should "get off the f***king road" while gesticulating and giving me two fingers. I was a bit taken aback by this, but managed to shout back "no, YOU get off the f***cking road" before he hurtled away up the road. Shouldn't be allowed out with anger management issues like that.
Then of course I was trying to figure out what I'd done wrong. Nothing, I was just riding along the road where I was perfectly entitled to be.
