At a T junction in a smallish but busy rural town square. I was turning right but also going to park into a parking spot about 20 feet on the left after the junction. The road coming from my left has a gentle curve to the right as I look left, this means I can’t see more cars more than about 5 - 6 seconds away. As I pulled out a Kia Sportage comes in to view but I had already committed and instantly indicated left and engaged reverse to have my reverse lights show I was planning to parallel park. Now the time between him seeing me and me starting to indicate and reverse would have been about 4 - 5 seconds. The Sportage did initially leave me space but then pulled right up to my bumper and sat there. The van behind them saw all this and left a very large gap for him to reverse back to give me room.
Instead the Sportage driver just sat there, after about 10 seconds he pulled into the oncoming lane and parked inches from my driver door. It was an old man and he started giving off about me cutting him up (I didn’t). His wing mirror was overlapping mine and I told him I was now unable to move without damaging both cars.
He started ranting about calling the police, to which I replied that they would be very impressed he was now blocking the oncoming traffic and preventing me from moving in any direction. The old man got out of his car and abandoned it to go into a nearby shop. He was at least a minute, by which time a crowd had formed and the oncoming car drivers were absolutely livid.
The girl driving an Audi A4 estate parked just ahead of the spot I was going into kindly moved out to let me move in. She then parallel parked back in again once I had parked, she was joking with me about the lunatic in the Sportage. At this point the old man returned and the van driver who was behind the Sportage was calmly telling him to “catch yourself on”* that at his age he should know better. He was also making it very clear that he saw the entire thing and that I had given him plenty of indication that I was reverse parking.
I told the old man that I had dashcam footage if he wanted to use it when he called the police. The van driver told me to let it go and walk away as it wasn’t worth it. He did give the old man a few more choice words about his childish behaviour before moving on himself.
* “catch yourself on” is. Northern Ireland term for grow up, or get a grip.
