Today I was driving along a 20mph road. I was driving a bit above 20 (Speedo 25 so probably 23) and the car behind me was aggressively tailgating me. They eventually overtook me and sped off.
About 3 mins later I approached a roundabout and spotted them in the queue waiting to go right. I was going left so drove alongside them in the left lane. We were stationery next to each other. I looked at them and did a sort of shrug gesture (like “wasn’t much point in you overtaking me, it didn’t get you very far”). This obviously wound them up, they proceeded to nose their car very close to me, honk their horn, then opened their passenger window and threw a hard object at my car. It must have been an open drink bottle as my car was wet where it was hit. No obvious damage, maybe a small scratch but that side of the car already has a few scratches from when I scraped it 8 years ago and never got it sorted.
We then both entered the roundabout and went on our separate ways. My 11 year old was in the car and was a bit shaken.
Obviously I now regret my little shrug action but I don’t think it warranted their reaction! It has really wound me up. AIBU for feeling stressed about this?
