Road rage, another case for a dash cam

[pegasus9]

It was a nice day here in so cal and had the afternoon off. Decided to take the 86 and go for a nice drive in the mountains.
On my way up the 2 fwy a fellow in what looks to be an Acura SUV decides to cut me off. Like too close for comfort within a couple feet. Ok, maybe he just didn't see me. So I switch lanes and go about my way. Well, as I'm exiting the off ramp the same car cuts me off deliberately and almost hits me! At this point I recognize it's the same Acura SUV that had cut me off. I'm thinking WTF and what is wrong with this guy. He proceeds to get out of his car and is charging toward me and the entire time I'm like this guy is crazy what did I do? He gestures to me to get out of his car and it's flight or fight. I am not gonna fall for his bait so I look in my rear view mirror and see there is no one behind me or any traffic headed my way. So I just reverse and go around this crazy fool! And he runs to my car and slaps my fender like a little girl. At that point i almost pulled over but said to myself that this guy is clearly crazy and maybe he just got out of jail. Anyway I went about my mountain drive and went over what the hell happened to provoke that fellow. Maybe he just didn't like being passed. Maybe he just doesn't like Porsches. Maybe he is just plain crazy.
Well I'm going to get a dash cam and put one in the 911. That way if anything like this happens again I can just submit it to the chp or police.
Do any of you run a dash cam in your cars? If you can recommend a good one I'd greatly appreciate it.

Thanks
