This might not be considered a near miss, it happens to everyone regularly, just wanted to get some feedback on how people respond. Riding down the left lane of a two lane road with a car on the right going below the speed limit. Car begins to drift across into my lane without indicating or looking. He came very close and I was aware he hadn’t seen me so I repositioned myself to avoid him. I then proceed to blast his ears with my pathetic horn which gives him a good fright and swerves back to his lane. He then gives me a sorry wave and lets me pass. What I was interested to know is, if you need to quickly respond to a crappy driver. Once you are safe do you let them know they’ve done something wrong or only use your horn whilst in danger? I always think it’s worthwhile waking them up and letting them know they could have killed you. Thoughts?
