Let me present a what if
fact 1: If traveling at 55 m/h (55 * 5280 ft per mile) / 60 min/hr = you will travel 4840 ft/min
fact 2: If traveling at 50 m/h (50 * 5280 ft per mile) / 60 min/hr = you will travel 4400 ft/min
fact 3: Traveling at 5 m/h (5 * 5280 ft per mile) /60 min /hr = 440 ft/min
assumption: a car length is 15 ft
situation: You are following a car that is going 50 m/h and the speed limit is 55 m/h. You decide to pass the car and not exceed the speed limit of 55 m/h.
How long will it take and the distance that you will travel in doing so.
I prefer the safety factor of 1 car length (CL) for 10 m/h, this means that I am 5 * 15 ft behind the car and do not want to pull back in for at least
5 * 15 ahead of the car (yes truck drivers hate folks that pull right back in front of a truck) plus the car that I am passing is 15 ft. so I will travel
5 CL + 1 CL + 5 CL = 11 * 15 = 165 ft.
Now let us figure in the distance that we will be traveling using facts 1 and 2. 4840 ft/min - 4400 ft/min = 440 ft travel per min is the difference between the car and you.
Now add the safety factor in and we have 440 ft + 165 ft = 605 ft. How long does it take to travel at difference of 5 m/hr.
Answer is 605 / 440 = 1.375. That means that you are in the oncoming lane of traffic for 1.375 minutes!!!!!!!!!!!!!!!
I do not wish to be in the oncoming lane that long.
If my math is wrong then please chime in!!!!!!

Retired highway patrol division chief told me this yesterday...........
He was traveling on a 4 lane interstate leading a pack in the number one lane doing 75+ passing slower vehicles in the number two lane. The posted speed limit was 70 mph. At the time, he didn't see the marked unit in the pack about four cars behind him. He could see more slower moving traffic ahead of him so he maintained his position and did not change lanes. Before he new it the marked unit pulled into the number two lane and rolled up beside him and over his loud speaker told him to speed up or pull over because he was impeding traffic. My friend couldn't believe what the patrolman told him. The rules of the road aren't what they used to be.

Safety in mind.
Surely any speed limit set on any road is to ensure that drivers do not endanger other road users.
If every driver was likely to get a ticket for 1 or less than 1 mph over the posted limit IMHO
it would create a situation where all road users are concentrating on their speedometer and thus
not fully concentrating on the road ahead and that is a very dangerous precedent especially at higher speeds. We know that
bike/car speedos are not accurate. Personally I tend to use the speed indication on my SATNAV
which is more accurate.

Some of you cry babies in the U.S. who want to speed all the time, chew on this--- as seen in Ontario----

That's 30+ MPH over the limit for us South of the Border folks. I would say, in most cases, that is justified. Now if only we could get the wrong way drivers and drunks off the road.

Why do we focus on the police doing his Job? Why not the 1 mile speeder, he broke the law?

As with all laws a bit of common sense should be applied. There is no way a mass produced speedometer could be manufactured with a tolerance of 1 MPH nor is there any way to keep the original error rate in place after a bunch of miles, change of tires, etc.
In this case the cop was using his LEO position to harass someone who was well within the spirit of the law. He needs an attitude adjustment.

As of this past legislative session in Idaho it is, up to 15 mph over the posted limit on a two lane, two way, highway. I don't know how far past the car you passed you can stay at the higher speed. I guess I'll have to find the law and read it.

I won't speak for other areas but on long island when you are on the northern state or long island expressway if you follow the
speed limit you would have a backup all day for at least 20 to 30 miles which would make the roads safer except for the fact
no police or ambulance outside of helicopter would be able to get anywhere in a reasonable amount of time and that backup
would probably run from 6am until midnight. These speed limits are made very generalized for drivers but perhaps if dmv were more strict on who gets a license the roads might be far more safe even if the speed limit were raised 10mph.
Safety isn't made up just from speed it is the vehicle and the drivers capability that is in my opinion equal or more important to safety.
I have seen many who perhaps text, shoot heroin or talk on cell while driving which if you are capable is ok but most can not drive and
do so and should not be driving no matter what their speed.

There is a certain municipality in my area that is mostly rural with single houses scattered here and there. 2 lane roads. Mostly farm fields and pastures. The general speed limit of local roads is 35mph with a one spot of 20mph for about 1/2mile approaching a single lane underpass, and 45mph for state maintained roads. Where is the common sense in that? The local police department makes very little attempt to enforce these limits. they are simply too silly to make any sense.

And what is that comment supposed to mean? you never knew there are those who text & drive, perhaps you should stay away
from the freebase or lsd.
oh i am sorry i didn't mean to get personal against your personal attack, i must be a real jerk to do so.

You can easily see what I was referring to because I quoted your sentence.
You said "It's OK if you are capable" after you mentioned text, shoot heroin or talk on the phone while driving.
I suppose you'll now say you were joking.

Again i am sorry you don't know obvious sarcasm, i admit it is my fault that you are not smart enough to realize it.
Now are you going to tell me that there are not those who are capable of talking on a phone while driving or fiddling with a radio
while driving if so i will agree with you and that police should pull over before using their radio. If you don't want sarcasm then i will say
this i don't think a police officer can correctly judge the speed of vehicle within 0.67mph accurately. If you are accurate 70% of the
time then remember when you get a c- in high school you are not considered smart, if your doctor is accurate 70% of the time how
much do you trust him?
Now please don't take this the wrong way but i think you are a schmuck and i very much respect the police and what they stand for
but i judge each on their own not just by the uniform they wear.
P.S. how do you feel about a police officer in his personal car that gets pulled over for speeding, shows his badge and is then
let go without a ticket? Are you in favor of prejudice or discrimination? Would you report the officer that let that happen?
