I hoped I would never have to use my dashcam (GT300W) because of something like this. But it sure came in handy now.
The story is that I was driving 30mph (which is the speed limit) and a girl driving an SUV slowed down at a stop sign but seems to have ran the stop sign, pulling right in front of me very quickly. I couldn't have known if she was going to see me and stop or keep going. I had a very short time to respond, and in that time I attempted to brake as much as I could. But it was too late, and I could not decelerate in time.
The girl's excuse is that she did not see me. The impact caused a minor injury to my right foot. I visited the doctor and it's only soft tissue damage, an x-ray shows no obvious bone damage.
