An incident happened a few weeks ago but it has really knocked my confidence (new driver) and I’m not sure if I did anything wrong or if I’ll be reported
.
I was driving in a 20mph zone and out of nowhere, a car appears right up behind me. The car was tailgating me, almost sitting on my bumper and wouldn’t let up. I felt really intimidated.
The car then stayed behind me but moved to my right and back in again, as if they were threatening to overtake me; at this point they were still very close to my car.
The road is a single lane road on a quiet street with residents’ cars parked down the oncoming road so although traffic can go both ways, the road is very narrow and it’s usually one car up then one car down.
At this point, I felt bullied and panicked so thinking I had possibly got the speed limit wrong and it was actually a 30mph zone (signs are not clear in the area) , I sped up to clear a gap between us. At the same time, the other driver started to overtake me. To the other driver I obviously looked like I was being deliberately aggressive and speeding up to stop him overtaking. It all happened so quickly. As soon as I realised he was overtaking, I slowed down to let him pass. He then thanked me 
I bipped at him as I was so annoyed at his bullying and also the fact I’d probably broken the speed limit because I felt so pressured. The road is really not suitable for overtaking. Upon checking the speed limit , it is a 20mph zone and I was doing the limit.
Now I feel like I’ve been “one of those” drivers and acted irresponsibly in return. Did I do anything wrong?
