I was driving to work one morning on an interstate highway. Both lanes were moving at the speed limit, which made a lot of drivers impatient. I usually drive in the righthand lane, about 5 mph over the posted limit; pretty conservative. Finally the pacesetter at the front of the line in the left lane moved over so that lane started to speed up. The right lane was still at the speed limit, which was even too slow for me.
I saw a gap several car lengths long behind me in the left lane so I signalled a lane change and moved left. This infuriated the driver who I moved in front of and he accelerated his turbo Saab hard to close the door on me. I didn't fully realize he had taken this action until I had completed my lane change and noticed him right on my bumper, screaming at me and gesturing crudely. I didn't engage in any return gestures, and as soon as I had passed the slower right lane traffic, I signallled and changed lanes to the right, leaving him free highway ahead. He passed, but cut in front of me and hit his brakes to demonstrate his wrath. I continued to not engage him, and only slowed to avoid his attemped contact. He then roared ahead into the distance. Stupid me, I thought it was over.
About three miles ahead his lefthand land of hares had slowed as it approached the portal of an under-river tunnel. All of us slower tortoises in the right land were being swept right past them. Sure enough, as I was about to pass him on the right he reengaged me, swerving into my lane in front of me and braking hard. I moved right in my lane, and we were actually side-by-side in the right lane; my wheels right on the shoulder paint stripe as we enterred the highway tunnel. Drivers behind us were slamming on brakes and swerving to avoid this maniac; some of them could have been injured if I hadn't done something to end it.
I felt I was under attack with a deadly weapon (his car at 55 mph) and slipped my pistol out of its holster in the passenger seat and held it up to my side window where he could see its profile. I never pointed it at him, or even gripped it in a firing position. That was enough to convince him that I could defend myself if he wanted to continue, he broke off his attack and sped to the first exit ramp. I never saw him again.
Was I justified in displaying the gun, or was I illegally brandishing? I felt I was under potentially deadly attack and displaying the gun ended the attack. I consider that the same effect might have been achieved by displaying the holstered gun.
PS I saw a turbo Saab just like his all cracked up on a flatbed truck about 6 weeks later on the same route. I'm kind of hoping it was him finally getting his just desserts.
