I'm in the market for something like this. Just last week my buddy was in a collision and his car was totaled. He was not at fault but it was a red light. The other driver who caused the accident lied about it and my friend was now at fault. Luckily he had a dash cam which recorded the entire incident and he was cleared. If he hadn't had it he would have been screwed. He would have been ticketed and his insurance would have gone up. Here is a link to watch the dash cam in action if you care. It's kind of interesting. skip to 2:25 to see the crash.
