I'm not saying anyone should lie. Very often our perception of what happens in the seconds before an accident isn’t always completely clear or accurate. It’s quite natural not to want to be the person that caused an accident and to blame someone else.
Often bad habits, of any kind, become ordinary and we don’t even notice them. Most of the time those bad habits that we have and the bad habits of the other driver don’t result in an accident, sometimes they do.
The post about using the camera to be a better drive is a good one. The camera would be a good tool to show us what bad habits we have so we could correct them.
