a minor example of this happened to me and my wife and kids in our mini-van about 2 years ago on I-664 in SE Virginia, at night. There were about 5 such bikers driving like fools around us, in crawling traffic, driving between lanes to bypass the full-size autos in traffic, and as the traffic started moving a bit, they cut in front of me, and kept slapping on brakes when the way was clear ahead of them, making me keeping stopping short. My wife claims she was as afraid or more as she has ever been in a car that night. A cop ended up pulling over one of them, and at that action, the rest of them zoomed ahead and got away, but I remember it was a tense time for us, and when this came out in the news recently, it brought the memories back to us again. Something like this can make you confident, there is NO time you want to be caught unarmed, period.
