Not driving without one now that I had an experience. Was driving to work, right lane slow, left lane moving good, so I saw a big opening after this one blue truck, so I got in the left lane and accelerated to where I was about 2-3 secs from the blue truck., I did notice the big Mack Dump Truck coming in the left lane as I got in but he was at least 100 yards back, probably a considerable amount more, and he was coming fast. I'm over the speed limit and he still gets right up behind me and does this weaving thing left to right and as he is the blue truck slams on it's brakes because someone cut in front of him. I could either get closer than a comfort level or hit my brakes so I did. Immediately got hit. Driver is out of his truck, screaming all kinds of things. Dude thinks he's a total badass and a rock star. He's telling me how I'm in deep poop. Okay. Police get there, DOT shows up soon after because they are always on that road. He starts on telling them how he was going below the speed limit and I cut in front of him and he couldn't stop. Basically saying I'm one of those insurance fraud guys or something of that nature. At this point he's calmed down and sounds like a logical decent human being. At this point it's his word vs mine because nobody else stopped. But, I have a dash cam. So the camera only shows front facing, but you can see the moment of impact at 57mph in a 55mph zone. I'd post the video, but it doesnt' show anything except you can see when we hit. Another thing it shows is that I was hitting the brakes because the truck in front of me did, and not some kind of road rage thing. I wish I had recorded his reaction, was kind of like a bit of "the gig is up" but then he's trying to figure a way to talk his way out of it. Officer gave him an opportunity to come clean, he didn't. So instead of following too closely, he got a reckless driving/road rage ticket. The let him employer take him back instead of arresting him which they normally do. He did start whining how he has a wife and kids at home and now they are going to lose everything because of ME. Yeah, I'm the bad guy because I proved him a liar. I don't know how I'm going to sleep at night but I'm sure it will be with my dog on one side and my wife on the other. Side note, thought my old chevy truck would be more messed up than it was, just pushed in the bumper a little, which I fixed myself with a slide hammer. No, I'm not going to sue talking about my neck and back. It's my old truck, not the one in my Avatar. Anyways, if I didn't have that camera, who knows. My word against his.
