I don’t suffer from road rage (not travelling by car in times of heavy traffic when I’m in a hurry helps a lot).
If anything, I suffer from road smugness. I don’t shout at idiots on the road. Instead I make smart-arse remarks, to myself or to others in the car. “Yeah, well done mate.” “What are you doing?” “Yeah it’s hard to reach the indicator switch, isn’t it.” “You can’t turn there, you know.”
I will try and hand signal people if it’s helpful. The other day I signalled to a lady who, after dark, hadn’t turned her lights on. She then did so. Just a bit further down the road the police were doing a breathtest, so I probably saved her a fine.
And I know I’m not the universe’s best driver. Occasionally my smart-arse remark will be a little more contrite: “Ooh. I’ve done that.”
