I've been in a few car accidents when younger, been knocked off a bike and bullseye'd a car windscreen when I was about 10 or 11. I also had an incident at a swimming pool when very young where I came quite close to drowning.
Most were related to car incidents, and a majority were my fault. Thankfully, I haven't caused a wreck before. I've done some dumb things that almost did though. I once pulled into oncoming traffic and one person had to swerve and one person had to put their breaks on, this was primarily due to a nervous situation. There was a time when a haybail caught fire underneath my car because I was too afraid to swerve into oncoming traffic to avoid it. I had to break hard due to an emergency vehicle and a lady crashed into my car behind me.
