Driver speeding 80mph + on a dual carriageway, 50mph speed limit.
Driver didn’t like being flashed to slow down so decided to ‘break down’ whilst joining the roundabout forcing us to be blocked in, sat there for 5 minutes.
When they finally decided to move, they slammed their breaks on whilst on the roundabout which meant we had to slam on and was very close to driving into the back of them. They then decided to speed off nearly causing an accident with another car. Extremely dangerous driving.
