a lot of the cops here that are undercover.. have normal plates. what really gives away is the INTERCEPTOR sticker on the trunk. and yes the hubcaps that only they get on the cars. Marauder'* here are only used by FHP. they have like 5 or 6. down here, you dont see to many civilians driving them anymore... mainly marquis'* and town cars... the cheif of police in my town drives a town car.. all blacked out.

(Please don't take this as a smear on cops in general, but our local fuzz has some screwed up priorities.)
I personally hate the term "Road Rage". I have seen very few cases that weren't started by the so-called "victim" doing something extraordinarily STUPID and dangerous in the middle of traffic.(Not saying this is always the case, or the case with you specifically, MOS)
I've personally chased down several drivers that have caused me to have to take extreme measures to avoid accidents.
The other day, I was driving to my Brother'* apartment, following a Lincoln at 70MPH on the interstate(yes, I know, 5MPH over the local speed limit, but I was following traffic speed), and some dick-head in a rusted-out Ford Econoline, going 50MPH decided he needed an exit at the last second. He yanked the wheel over, almost hitting the Lincoln and forcing the little old lady driving it to veer onto the shoulder, and forcing me to lock up my brakes to avoid hitting him. I reacted by tailing him while calling 911, and teling them what just happened. I was transferred through three departments over the period of 15 minutes, and finally told to stop following him because he had called 911 himself and reported somebody following him, trying to run him off the road. Crap, of course, because I never got closer to him than 50ft.
Now, what does that say about the priorities of our law enforcement community?
Does this make me more dangerous that the guy in the van?

Personally, I think you pretty much handled that pretty well. The problem the polce have is that it was your word against his. Without any physical proof of what happened, they could spend days listening to each of y'all tell your side of the story, and never know what really happened. Granted, not all cops react to a situation the way you think makes sense, or actually does make sense, but they are human and, in my opinion, do a pretty good job in general. There'* just too many morons for 'em to keep up with sometimes....

My hope/wish is that a moron like the guy in the van doesn't see the unmarked car, so figures he'* safe, and pulls a stunt like you described. The next thing he knows, his mirror is full of pretty, blue, blinky lights....

I've actually seen it in action, and it does work. There was a whole group of us, 7 or 8 cars, cruising towards the cities, doing about 10 over the limit, in a nice polite group. The car in the left lane, about one car length in front of me, was an unmarked Trooper. He was pacing along with the rest of us, not "saying a word" as it were. Well, all of the sudden some moron comes screaming up behind our group, had to have been doing 90, flashing his brights expecting us to get out of his way or something. Well, as soon as he got close enough, the Trooper flashed his lights right back at the moron.

Made my whole trip, it did!!

I should have elaborated a little. The guy in the van was still driving erraticly while I was on the phone with the cops. He blew a red-light, cut off several more people, and never got up to anything more than 10MPH below the speed limit. If a cruiser had responded, they easily would seen this behavior and pullled him over for reckless operation.
Cops in Columbus DO NOT respond to fast-mover or reckless-op calls. They don't pay money like speeding tickets do, and the CPD wants REVENUE. If someone isn't hurt or dead, they don't wanna hear it.

you want sneaky........the troy , mich p.d. uses a camero to patrol i-75.......no light on top to see it from a distance.

i just use a combination of paranoia around crown vics <all they use down here, they have one, maybe 2 cameros> and a good ole fuzz buster teamed up with a spirit wind 2. dunno if it actually works yet though.

Yeah all the highway cops on i-95 in philly don't have the lights on thier roofs. For the most part there impalas. and i've seen a couple crown vics with lights in the grill pull people over on 95 too. If i see a big ford/mercury car without LM (limo) on the plates, i slow down and if i see a white impala i do the same. It'* weird, the cops have ford taurus' for work cars too .

My uncle got pulled over by that cop. I was in the car with him when he did. For a ticket, it took him nearly 30 minutes!!!

i have been known to have quite the lead foot, i wont even mean to and all of a sudden find myself near 100, i havent gotten pulled over tho, even passing speed trap cops, i guess the bonne doesnt stand out as something to pull over like a sports car would. .i slow down for crown vics, grand marquis(never seen a cop one but from a distance they look just like a crown vic), impalas, definitely caprices, no camaro or vette cops near me but i am wary of them when im out of my area
