I'm usually 5-7 over at the most. I have a CDL and need it for work so I try to be mellow. And if I'm towing with my personal truck I go slow just to save gas.

I was just rethinking this and usually I go with the (faster) flow pack until one or a few of the flow group starts to block in others in the group or hang on the side (and in the blind spot) of a semi or cars that should be passed and then get into the right lane and out of the way. I try not to impede the flow or speed of others that want to go like H#ll and especially never block or take away the run of a semi even to the point of slowing down and flashing the lights to let them out to do their passing. I don't care if I have to slow down to their speed as they slowly make it past the slow moving right lane vehicle, I'll make it up once they pull back in the right lane. People that block the left lane no matter how slow or fast they might be going p1$$es me off more than anything, Go as fast or slow as you want or feel comfortable but d@mnit don't impede the flow of traffic and stay the heck out of the left lane(s) once you have passed! You do that on the Autobahn and watch what happens. There are even State laws against staying in the left lane(s) too long.

I find that car enthusiasts usually drive 2-10 mph over the limit, while non-car enthusiasts drive stupid, they just don't realize that driving a vehicle is THE MOST DANGEROUS thing they do in their entire lives! I used to work with automation and other things that will kill you if you don't pay attention, while the general public doesn't work around things that will kill them and they have little idea that they are tempting fate...

I drive anywhere from “conditions allow” to 30 over. I live in a rural area but very cold winters. Little to no traffic, but big animals, gotta be careful, but gotta live your life. Fast cars deserve respect, as does your life.

I was a no-more-than-5mph-over guy for a long time, but 30 years of a mostly-highway commute have ruined that. Now I pretty much pace the traffic, which, when there's not a lot of congestion, is going to be about 10 over. 65 in a 55, 70 in a 60, that sort of thing.

driving today at the same speed (80) in the same place and 2 vehicles (one was a cement mixer!) were pulled over within a mile of each other, so i slowed down! I forgot to say in my op the speed limit was 60.

A longtime ago I was on the Ohio Turnpike cruising around 10mph over the speed limit with no one around in front of me. All of a sudden a mini pickup truck with another car following him so close I thought he was towing the car. They went by me doing about 20mph over the speed limit so I waited for both of them to get a 1/4 mile or so ahead and picked up my pace to match theirs. only traveled about a mile or two when I see a Trooper step out from his car parked on a service access right next to an overpass. He of course steps out and waves the two over and I had an Escort radar detector that was silent as I jumped on the brakes and the officer was still just standing there??? Yep he pulls me over, I take down the radar detector and pull to the front of the line. He walks by the two and up to me and says where are you going? I said (and it was the truth) "Going to a job interview" Trooper says "We got all three of you by aircraft, but you just joined the other two not to far back so I'm going to let you go". Pretty tough to spot aircraft but I still try to keep an eye out for them,

As a long time Class A CDL holder, which means I am never allowed to have a moving violation dismissed ( guilty or non-guilty only) or mitigated by taking driver school with even a reduction of points, no matter what vehicle I am driving or even if not working, I seldom intentionally drive more than 3 mph over the limit and try not to ever be the fastest car in any pack.

It sucks, But I don't make the rules, and I have too many vehicles the insurance could increase on based on points, even though I only drive one vehicle at a time.

Would've been interesting to put a poll on this question

Most drivers do not seem to care at all for the extra $ cost of going 80 mph in a non-aerodynamic vehicle.
The high gasoline price jump period we just went through gives “real world proof” of that.
Many drivers paying high interest payments every month on the debt they owe still have “the pedal to the metal.”

It is kind of a curse to be interested in aerodynamics.
Tiny details of car shapes grab your attention as you walk through parking lots.
You can’t float down a river without noticing unusual eddies.

lol, I doubt one tenth of one percent of the vehicles you see in the parking lot are non-aerodynamic. Aerodynamics have been a focus at least since I bought my brand new 86 Daytona.

My 2015 535i has a lot of aero tricks you are not likely to notice stumbling thru the parking lost. Grille shutters and belly pan come to mind.

i don't know how aerodynamic my "bus" [99 caravan] is, but i get 26-27mpg all the time, loaded or empty, interstate or in town.
3.3 flex fuel engine, although i have never ran E-85 in it, just the cheapest regular gas around.

10 over

By myself I always run about seven over the posted speed limit. I use cruise control whenever I can and I just let it maintain for me. Do the same when I can riding my 2007 BMW R1200RT. Never had any Wisconsin police officer, local/sheriff/city/state-cop ticket me for seven over the posted limit. I stick to the "seven you're fine, ten you're mine" guide when driving. When on my bike I always wear a white full face helmet, my silver/grey Olympia riding jacket, gloves and Euro style riding boots, and if I wear black jeans I swear some drivers think I am a cop on a bike. My BMW is a mix of silver/grey colors and I have LED driving lights added to the front. I never follow traffic too close, but I have had cars pull over to the side or to another lane as I approach, heh, heh.

In my company provided cars over the years, I just blend into traffic because what I drive is very common, don't stand out in traffic. When in traffic I drive with the major flow as its easier to maintain space around me. So if traffic flow on major highways/interstates are running close to ten over I tend to flow with them. I was recently driving 294/94 around Chicago and north, traffic flow was averaging ten+ over the posted speeds, which means in many sections we were doing 80+. I saw a Metro police Ford Explorer behind me in traffic, so I slowed to within eight over the posted speed and the police Explorer zipped by me easily ten over the posted limit. In fact it was two of them running a close formation moving through and around traffic. Once they got ahead of me about 1/4 mile I sped up to match their speed, and we were doing 85+ in a posted 70 area. Curiosity satisfied I backed off down to seven over and set the cruise.

When I get my 56 pickup on the road it'll easily cruise at 70+ all day because it'll have a Dakota chassis underneath with a built 5.2 Magnum/8HP-70 trans with 3:55 gearing in the rear axle. But since it'll certainly stand out in traffic I may hold more consistent to the seven-over limit, as long as I don't have traffic crowded around me (I hate that when driving).

my one buddy just got a new chevy pickup several months ago, and he is constantly having to slow down from 85. interstate limit here is 70.
that thing rides so smooth you don't realize just how fast you are going.

My work truck got changed from a 2016 Silverado 3500HD to a 2022 3500HD. For whatever reason the newer style truck seems like it is going way slower. I have gotten used to it now but I really had to watch it for awhile. The truck doesn't ride any smoother than the old one but something with the dynamics of the newer body style changes the perspective of speed.

i keep telling him to use the cruise control, but that damn "infotainment" thing has him so confused, he just gave up trying to figure it out.
too much garbage on those things in my opinion.

The cruise control buttons on mine are just normal buttons, no tricks! lol

I have a 2022 Silverado work truck. Cruise has nothing to do with the screen. It's buttons on the left spoke of the steering wheel.
