5mph over on all roads except interstates and residential neighborhood. Interstate is 5-7 over. Residential and I'm right at the speed limit, never over my

Coming from who wrote that, that's hilarious.

+10% is the margin of error that is the approximate tolerance that is built into most speedometers so they will always read a higher speed. This is to compensate for tire wear, wrong tire size, incorrect tire pressure, etc., or to never read a lower speed than the vehicle is actually going. If this was not the case (of reading a slightly lower speed) then there would be lots of class action lawsuits for speeding tickets. I use the +10% too because of this. Lots of adventure and touring bike riders have GPS and they are always complaining their speedometers read a lower speed than their GPS, and that's because of the of the speedometers built in margin of error. If you have a GPS with a speedometer check it against your speedometer. GPS speedometers are also not always perfect but it may give you an idea. Or set the cruise on 60 mph and stopwatch check it for 60 seconds between mile markers. Or 51.4/52.9 sec @ 70 mph this way if you think you were going over 75 mph when you passed that cop you may not have been and that's why he never went after you. Checking your speedometer's accuracy is a fun thing to do on that boring long haul drive

Ya it is,

I really don't like to use the Interstate unless there are no good options. Then I run with the traffic, I like to pick a group of cars that look to be running together, then drive at what ever speed they are moving at, that is often the posted limit +10 mph. If I am by myself its usually limit +5.

Cruise won’t set past 85. Keeps ya honest

Faster than most
I'm luckier now than I was when I was younger, I haven't been ticketed or stop much in the last 30 yrs.
Maybe it is the vehicles I drive now

What was the $ amount and year of your last ticket?

Convert old tickets by how many vending machine Coca-Colas the $ would buy in that year.

Advice: do not drive 123 mph on dead straight Alligator Alley in the middle of the night without knowing about the speed trap the Florida Miccosukee Indian Tribe raises money with. You may wish to calculate the Aerodynamic Drag Cd but that is not the “best” way.

I'm in upstate NY. The Thruway and Northway speed limit is 65. I hardly ever drive less than 75 true speed.
I'm observant enough that I've almost never passed a speed trap at 75, I slow down to 70-72..

I drive my vintage cars around 72-73 because they get too much attention.

I usually follow the flow of traffic, 3-5 over the limit if there isn’t much traffic.

I paid for the whole speedometer, sooo now and then I use it. Seriously though, I drive a CV and it has radar on it, most vehicles that pass me are in excess of 80-85. Occasionally I see them top 100.

i am getting old.............
i used to just blast down the road, but with today's distracted drivers, i might get to 5-8 over, but that's stretching it.
way too many things to watch out for, and i realize my reflexes are not even close to what they used to be.
however, i have proven that when evasive tactics are called for, the look where you want to go rule really works !

On a thruway/highway, if I am not on a long trip, I am content with 5 mph or so over the limit.

If I am on a long trip, I will go with the traffic flow up to about 85 mph, I don't like going faster than that (although honestly I don't even really like going that fast, I prefer 75-80 mph; you don't realize how fast even 80 mph is until you are wishing you were stopped).

Usually follow the rest, if there is no "rest" of traffic I'm going 8-10 over

I set the cruise control to the speed limit plus 2mph.

I stay to the right, except to pass.

I run 10 mph over the posted limit usually.

Same here.

That's mostly where I run if I have running partners on the interstate, but I watch my P's & Q's going thru your neck of the woods on 76/501. Had too many close calls with the SC Silver Bullets....lol. Especially in the 50 mph zone around Sparky's!
