Who is being unreasonable in this situation?
Car A (large, transit sized) indicated and turned left into a very narrow side road. There was a parked car half on the footpath on their side of the road, and a car waiting to pull out onto the busier main road. Car A is partially obscuring this drivers view trying to pull out due to where the parked car is (on a blind corner 🙄).
Car B (very small car) is almost level with the parked car. Nothing behind them. Car A waits for car B to reverse back but the driver doesn't. Car B then moves forward to behind the car waiting to pull out, despite car A gesturing for them to reverse back to allow them through easier.
Car A may have fitted through the gap, but it would have been very, very tight. Car B driver then shouts at car A driver they "would have got through" and "they need to learn to drive". A short heated exchange then occurs until car B is able to finally move forward.
So who was in the wrong here?
Car A - they should have tried to drive through the gap
Car B - they should have reversed to allow car A though with more room.
