It was the car wash thread that got me thinking about this. I've had one for quite a few years now. Not needed to use it yet though there was one time where someone changed lanes right in front of me and I had to take avoiding action. He then raced off. I pulled the video when I got home and saw I was behind him earlier with a GREAT view of his license plate and had seamless proof that it was him who later made me take avoiding action I got rear ended too, twice in fact and it would have been interesting to have a rear facing camera to see if one of them was texting, although both people admitted fault - Not like they couldn't really Question 2: If you DO have one, have you caught anything interesting on it?
