All of this is why I ordered my 2013 AWD hemi charger when the old tired 98 Expedition was getting replaced.
On a 4 lane road, it is better to just slow down if you are on a longer trip and let the clowns get annoyed and their ADD will kick in, they will speed off. You can speed up after, they will have forgotten about their retardation by the time you catch back up, if you do.
On a two lane road, you have to judge the situation. If it is actually impossible to pass anyone, best bet is to slow down so far they get bold enough to go around, let them get in front, and then follow at a safe distance. If you can pass, 99/100 they will not have the guts to do it so you catch whoever is in front and then pass them. Now the guy you passed gets to deal with the retard tailgater. I call this "peeling them off". Passing the guy in front and peeling off is a much better, and satisfying, resolution- especially on shorter trips.
The alternative to all of this is a 10 second excessive speed maneuver. On a two lane road, tailgaters have a "I am scared" limit of about 71mph. So a ten second burst of 90-95MPH and a "coast down" back to the speed you had the cruise set at will leave enough space they likely will give up on trying to "draft" you. Similar to passing someone else and peeling them off, but you need a bit more speed to create a distance far enough they lose focus and their ADD kicks in.
On a 4 lane, this is a bit more difficult because 65mph means the "I am scared" limit of these retards is closer to 85mph, maybe even 88. This is why I suggest slowing down on a longer trip. On a short trip, F'em if you are confident in the area and know you won;t lose a license to a ticket. Usually, in the case of the guy that wants to drive right next to you- flooring it and pulling away at 30mph faster then what you were doing before for even 5 seconds is enough to give enough distance they won't try it again.
Too add to all the above from this post of people's observations, I want to include "that guy with the trailer". I refuse, utterly, to follow any non-semi trailer of anything. Heavy stuff seems to have rocks or otherwise fly off of it, lighter stuff people don;t secure loads or tow it with something with no adequate brakes or otherwise. Or my favorite, loading like a compact tractor onto a utility trailer rated for like 2500lbs, or loading down a garden trailer with bricks from the hardware store, and similar things where someone has not only exceed exponentially the tongue weight of the trailer, but likely the tires. Of course, this last person will also be running 5mph over the speed limit. Watch and cringe as you see the tongue of the trailer flexing at every bump like it is made out of plastic. Grip your wheel tighter as you notice the tires are bulged out to twice as wide as they would be running empty. They will also become enraged when you pass them. ALWAYS leave excessive distance behind you when you pass them, they WILL speed up to an even more out of control speed. I think this stems from small peen syndrome where they get upset that their vehicle has lost whatever semblence of performance they thought it had after hooking up 4-6000lbs of **** behind it as they do not understand the basic law of acceleration: light weight.
I have seen a coworker and a coworkers son get killed due to retarded trailer drivers in my lifetime. One was driving "just down the road" with an unsecured snowmobile that, really surprisingly, fell off the back of the trailer when they hit a bump DOING 65MPH ON A COUNTRY ROAD. The other was involved in a multi vehicle pile up when some retard was pulling a camper with their 4cyl. short wheelbase jellybean and it started fishtailing and everything went sideways. That one was more of an accident, a stupid one but if the driver had kept the speed to a reasonable level it would not have happened. The snowmobile was criminal in my opinion.
But there are plenty of retards that don;t understand towing. An ad for an SRT10 came up recently that caught my eye because of price. 22 year old kid had swapped his extended cab to a 6 speed. Put an exhaust on it. Then proceeded to hook up 26,000lbs worth of double car length enclosed trailer and drive it from Colorado to southern WI at 95+MPH FOR THE ENTIRE DURATION. He was super proud of this, but then said his mechanic told him it ruined 6TH GEAR on his brand new swapped transmission, so now he wanted to sell it. That is right, the kid hooked 13 tons of stuff to a half ton truck and used over drive to pull it at 95mph on the interstate across half the country.
ALWAYS pass the trailers. NEVER trust the trailer towing driver to be a reasonably intelligent human. Leave them in the dust.
