One day I was driving down the street and the car in front of me decided it wanted to turn right. I began to slow down and match it’s speed as you don’t have to completely stop to turn unless there is a stop sign. So as normal I slowed down and the was no stop sign so they should have just turned off but they began to stop completely and it caught me off guard. I quickly before hitting their bumper swerved into the next lane. I was shivering from that point on.
