I really messed up tonight. I almost hit a car when entering a mini-roundabout. I thought I had checked it was clear, and I just don’t understand how I didn’t see them coming. Then to make matters worse I went to hit the brakes but ended up hitting the accelerator instead (automatic), and very nearly went crashing into them. They stopped and remained stationary for a minute. I was anticipating them getting out to shout at me or something but then they just drove off. I am genuinely mortified at myself for being so careless and intend to take some refresher lessons with my old driving instructor. I am aware that I don’t have to report a near miss but I’m paranoid they’ll report me for careless driving? AIBU to feel worried about this?
