Im inclined to think they are targeting whoever happens to be in front of them at the moment, when the coast looks clear to do so. Not sure they have a particular targeting method,but it would be nice to find out..
The funny thing about this is I half-thought I was about to have one of these situations a few nights ago. Turned out not to,so no harm/no foul. But it got me to thinking such a scenario over, and taking a closer look at placement of my sidearm when in the vehicle for most effective draw/use if needed. (never bad to update/review such things,no?)
And then today-here's this article. Interesting timing...
Now, at the time, my pistol is where I normally keep it-clipped to the right-side of my seat .
When a truck kept creeping right up on my tailgate-no matter what speed I was doing, I initially thought it just a tailgating jerk. But...the thought crossed my mind of a bump-stop tactic as I approached a traffic light, and he didnt slow down much.
So, I reached down and dropped the saftey,but kept the pistol in the holster-at my side-ready to go just in case.
The wife saw this and looked at me and said I was paranoid..I described the tactic,and said it was caution,not paranoia.
So.....
