To be honest not that much, just being ignorant
I was behind a group of 4,3 in line, one in the middle of the lane. Fair enough, they were doing 20—25ish, so I was sitting behind them, but then when we came to the junction, lights on green, they suddenly stopped, no signals or indication why, and the guy in the middle of the lane was just there, lights still on green, then they chatted a bit and pulled onto the pavement, lights now on red.
As I was sitting at the junction waiting for the green, another group arrived at the junction. It’s 2 lanes, right lane for right turn only, left lane for straight and left. Most of the group was alongside my car on the left or behind him and my car, then another one, just as the lights are changing comes on my right, pulls in front of my car and just sits there then starts chatting to the guy to my left. I have no idea where he’s going as he seems to be with the other cyclists. Lights have been green whilst he’s chatting, so I beep my horn
Like I said, I need to chill out, not just while driving, in life generally
