Cruising on the I-75 from Miami to North at a confortable 85-90mph I reached a heavy traffic. Instead of slowing down, I started to pas them from left-righ and speed up a few times over a hundred. I tried to avoid the left lane but sometimes you just can't ! I got behind a Burgundy Ford Taurus and saw something interesting ! He turned on the red-blue light in his rear window and was pointing with his hand to the right. I got the notice and starter to think what should I do ! I immidiately made a quick lane change ... and an another one, and saw the result. My quick lane changes caused a chaos and he was blocked in the left lane, and was unable to change lane. I quickly headed for the nearest exit and took of at 100Mph. I saw him, trying to get out and make the exit, but was too late, he missed ! I headed to the Turnpike and got home safely ! Now how the hell was he ? Driving in a Taurus and having a red-blue light ? Was it legal ? Can he stop me in a civil car ? I mean what if he was a fake cop ? It happend here in S. FL and got a nasty ending ! The fake cop took of in a person's car and left a stolen junk for her/him. Also he got the clothes, purses, jewelry and every valuable from the car. So what do you think ?
