I’ve already committed that URL to memory.
So there 
I had something similar happen to me. Was going 15mph over through an empty road, cop passes me in opposite direction but in rear view window I saw him do a U-turn just as I crested over the hill out of sight. But since I was going home I just took the normal right to get home rather than go straight and let him catch me since I assumed he followed the road straight since he would have no reason to turn right if he didn’t see me go right. I didn’t hear or see lights though so legally what was I supposed to do, just go to the shoulder and sit tight as an admittance of guilt?
One time a police car followed me for a few miles with his lights flashing. I thought he’d use his siren if he wanted me to stop, so I kept driving. When I finally took the hint and pulled over, I told him I didn’t know what the flashing lights had meant. I was 17, in pigtails, and looked very innocent. Turned out he’d stopped me for a burned out tail light.
I purposely evaded the police twice in my life and that’s all I’m gonna say about that.
ISWYDT.
A few years ago, my oldest brother’s wife called from the farm. She had fallen and couldn’t get up. I wanted to call 911, but she told me not to do it.
So I drove out to the farm to help her out. 20 miles at about 100 to 120 mph the whole way. By the time I got there, my brakes were fading so bad that I could barely stop.
About three minutes after I got there, I was checking on her and trying to determine if she had broken anything and if I needed to take her to the hospital when a deputy sheriff stepped in the door. He watched for a couple of minutes and then left without saying anything.
He must have chased me most, if not all, of the twenty miles, but I never knew he was back there.
I can’t know what the law is in your state. My state requires all motorists to yield to emergency vehicles sounding sirens or flashing red and/or blue emergency lights. If they are not behind you with lights and sirens there is no reason to pull over. If you believe he is coming after you stopping is not an admission of guilt. Saying “I know I was speeding so I pulled over” is an admission of guilt. “I saw you make a U-turn so I pulled over” is not. I have mentioned many times how admissions on traffic stops are way overblown in the minds of the public. In 25 years I have never written a ticket where someone admitting wrongdoing to a traffic offense meant anything. The officer may be appreciative that you didn’t make him chase you down. I know I would be and I would be more inclined to give you a break.
Getting a traffic ticket is not that big a deal. Being charged with eluding is. In my state its a 3rd or 2nd degree crime.
Many years ago I was visiting my grandparents in a very rural area and saw a deputy sheriff motorcycle cop set up with a radar gun at the end of their driveway on a little two lane road that was the main drag to the next town. He was standing beside his motorcycle with radar gun in hand checking the speed of the cars coming down the road. When he caught one speeding he would wave them over with his hand. Every one of the people he waved over went up to the next driveway, turned around, and drove back to where the cop was still standing to get their ticket.
I’m sorry, but had I been the one being waved over he would have had to have gotten on his motorcycle, turned on his lights, and come after me. At that point, I would certainly have pulled over when safe to do so, but when asked why I didn’t pull over when he waved at me I would have said I thought he was just being friendly so I waved back.
In my county, we pretty much wave at everyone anyway. And they usually wave back, including the sheriff’s department.
I suspect if you were in trouble, you’d know about it at the time or at most within a couple hours. Relax.
In Florida, it’s a third degree felony. It’s bumped up to 2nd degree if you are speeding.
But the key is to prove you had reason to know the cop was trying to stop you. Lights and/or sirens behind you would certainly satisfy that element. Seeing a cop off in the distance just driving would be on the other end of that spectrum, I would think.
ETA: And if you respond to him by turning off somewhere and he decides to keep driving, as the OP describes, I don’t see how you failed to stop. The cop was the one who drove off.
Generally speaking, if they can’t prove it was you driving, you’ve got reasonable doubt as far as criminal charges go.
So if the officer recognizes your vehicle the next day and pulls you over, while he may write you a ticket, you’ve got a good chance of getting it dismissed. Or runs your tag and tracks you down at home.
Unlike parking tickets issued to vehicles, moving violations are issued to individuals. Note that this has a point of contention concerning stop light and speeding cameras. Some jurisdictions require a clear picture of the driver as well.
