That last picture is quite disturbing Dingo.
As far as getting cut-off, that happens every day. It's called rush-hour!
I love my T4R, but I'm not going to die in a hail of gunfire, or get acquainted with Bubba in a jail cell because I flashed my piece because someone simply got too close to it.
Anyone who's been through a concealed carry class will hopefully tell you not to pull your gun unless you are in serious fear for your life (not your vehicle's). I don't remember the instructor mentioning knives, but I can imagine that would get the Po-Po on your ass in a hurry as well.
There is a definite gang presence here in the Little Rock area so I like to be armed just in case. But I think if you go around playing Billy Bad-A S S & showing your pistol any time you think someone is too close to your truck you might just wind up on the ground leaking badly, or making new friends in a 6x8. You just have to use common sense.
However, I have to say if I was driving and someone flashed a knife to me I'd probably laugh, call the cops to tell them I was threatened and in fear of my life, then follow them to tell them not to bring a knife to a gunfight!
