Oh my God!!
I know how scary this is, I had several similar situations, one real bad about 2 years ago, thought I was going to be murdered.
I notice more and more people are getting insanely aggressive with their driving, I like to go fast on an empty road, but follow the speed limit the best as possible (maybe a little over it) and yet for some of these people that is not fast enough, they do the "light show", tailgate, cut around you and yes, slam on the brakes, looking to provoke an accident, heard this is a new scam, I shake my head . . . and say to myself, "what the hell is happening"? And I take meds? These killer drivers need meds, grrrrrr!
I have driven down in the area that you mentioned, and 95 gets pretty scary there near VA border, I sympathize for you.
Well, you take care, try to make some time for relaxation.
Also, don't laugh at those kind of drivers, it irritates them more and become hostile, I've been told, do not look at them, avoid eye contact.
Sometimes it works, but 2yrs ago I had a crazy truck driver, cussing at me, and said, "hey *****, I'm talking to you" "you hear me"?? and he went on and on about it because a local road merged, I guess he didn't know how to read signs and claimed I cut him off, while actually I was in proper lane and doing proper speed, he was the one barrelling down the road
I had a guy in a pick up, follow me down one of our rural roads, on my tail, he had the chance to go around me but obviously preferred to scare me, I pulled off the road, and finally he sped pass.
Oh, I can spend all day telling my horror stories of road ragers.

Stay safe now,
