I Accidentally pulled out one someone in a 30mph road, after not seeing/noticing them while doing observations it was too late, there was no collision but they did have to slow down, they did not beep or have any incident of road rage, after putting my hand up to apologise we both drove off as normal, although it is my mistake and a genuine accident they seemed to be going above 30mph due to how quickly they came in, I am concerned they will report me for careless driving, I did not notice a dash cam and although they had to slow down nothing else came of it, what do you think?
