Well I was pulled over today because a cop yelled at me and said he had to do a 110 to catch up to me. We had traveled about a little less than .81 miles by the time he caught up and pulled me over. I was not doing 110! For one my clutch is slipping so I couldn't do 110 if I wanted to! Since he said he had to do a 110 to catch up to me from 0 mph he was going to write on the ticket that he paced me at 110! So now I want to fight this ticket. For one if he said he "paced me" then legally that would mean him following behind me matching my speed and he said "he had to do 110 to catch up to me". Which means he was not "pacing" me. So now I call for help to calculate the speed at which he would have to travel to catch me if I was doing 60.


anyone care to help?

thanks,

bryan

 

Interesting, the cop was going 110MPH on a freeway? A bit excessive for just catching a speeder, huh?

Year 1998

 

he accelerated from a stop. I saw him the entire time but didn't think anything of it because I wasn't speeding heavily anyways. I was doing about 60 and the road had no other car on it for a good mile. I think if I was going 110 it would take a lot longer than .81 miles to catch me/stop me. That cop was so full of shit...

hah.. 110 and u thought u were goig 60?!.. thats a bigg difference..

 

I'm beginning to think that it would be worthwhile to carry a small "dictation style" tape recorder in the car. Keep it somewhere and you turn it on then just drop it on the floor or tuck it into a pocket somewhere in the car.

In the S with the top up, that would be easy, you just need to be able to do it in such a way the cop would not think you are going for a gun or something while watching you from behind. This would be something you do while pulling over, not after you are stopped.

It might be interesting to see what the reaction of the cop would be hearing those kinds of comments being spoken in front of a judge. But then again, it would not surprise me to see such evidence not allowed in court.

 

Ok let me get the numbers straight.. from start to stop you travelled .81 miles? 74 seconds total?

Well, since you had a running start, if you were doing 110MPH, and according to the cruiser's capabilities, he could never have caught up to you. Get some authoritative specs on that car. I found the above on a quick internet search. If he stated he had to do 110 to catch you, and you were doing 110, then how did he catch up? He'd have to go faster to catch up, right?

Here's what I came up with. The curve fit for the acceleration above is (roughly):

Speed MPH = 29.333Ln(seconds) - 7.5301

Anyhow here's the time distance chart:
Blue is the cop
Yellow is you at 60MPH
Pink is you at 110MPH

Cop is accelerating according to the times given for a Police model Crown Victoria.

X-axis is time in seconds
Y-axis is distance in feet.

Where the blue line intersects the pink or yellow is where he's behind you and lights you up.



As you can see, somewhere about 25 or so seconds after he takes off, he catches up to you at 60MPH, assuming he took off just as you passed him. But at 24 seconds he's doing about 90MPH tops.

As for 110, by the time he matches your speed, you'd have about 2000ft of distance between you (1/3 of a mile), and he'd simply never catch up.

It does get interesting if you were traveling at 80MPH:



At that speed, he'd get you in about a mile like you said (5600 feet), and he'd be travelling at about 109MPH at the time.

 

You might have a serious problem if they convict you.....

In Fairfax VA (and I'd imagine the rest of VA) they want 2 days in jail for every mile per hour over 90.......

Trust me....
