I responded to this Pet Peeve before:
It's part of the reason that I now want to be a driving instructor in the future, specialising in Anxiety learners to help the ignore other people's impatience and ignorance when driving and teaching non-Anxiety learners to be more patient and forgiving with other drivers. I'm now close to doing my practical test, yet I still get bullied on the road, often by people who don't have a clear view of the road ahead, my dad has come in the learner car with me and my instructor and he was surprised by the amount of aggression I received from other drivers and I wasn't even driving at a busy time!!
Maybe there's a yellow box junction and their exit is blocked, you're not meant to stop in a yellow box junction so often you DO have to miss a green light to avoid blocking the road later on! This happens often at the traffic light junction near my college, there's a bus stop right next to the opposite set of traffic lights and at 3:15 PM when students are getting on the bus, a queue is often blocking junction for 2 to 3 traffic light cycles, so people have no choice but to wait!!
So thanks for saying that I'm dumb since I don't have the red-green colour blind excuse. Hopefully this is just you speaking after a stressful day along with a stressful drive.
More Pet Peeves:
-Queue cutters, having to wait for lunch at college can be really annoying as people jump in the queue so they can be with their friends! (I hate waiting for my lunch

)
-Cyclists, half of them in the UK don't seem to know that they have rules to follow, heck there is a WHOLE SECTION of the Highway Code dedicated to you guys, follow it so I don't get yelled at when YOU'RE IN THE WRONG!
-Christmas adverts, god they are so repetitive, nauseating with the amount of food shown and shown way too early!
