Ah, good ol' Drivecam. We have them. I used to think that there was some kind of game going on to see how close you could get to my truck when darting into my lane. I've even had instances of douchebags on bikes do it. If there was a crash, it would of course be the evil truck's fault. With Drivecam, I say bring your stupid ass on over. While writing this a commercial for one of those "ambulance chaser" law firms was playing. "Have you been involved in a crash with a big truck?"
I hated that thing when I first started but I've got to say it has made me a safer driver. And it is a double edged sword - great if you weren't at fault in an accident but if it was your fault? Oy!
I give out an informal award occasionally for the driver with the closest call who doesn't unlease a tirade of F-bombs.
