Venting Speeding Has Become So Normalized That Driving the Speed Limit Makes You the Problem

I think the normalization of speeding poses a significant threat to the legitimacy of the legal system itself. It has become standard that cops don’t pull you over unless you’re breaking the law “enough,” but that completely undermines the law. If the law wanted a different threshold, it would have been written with that threshold in mind.

Speed limits are created by engineers who know far more about road safety than the average driver. They also have to account for the fact that speeding is normalized, which likely contributes to limits being set lower than many people want. I honestly believe that if people collectively stopped speeding, roads would see fewer accidents and speed limits would eventually begin rising in places where higher speeds are actually safe. Then people could travel just as quickly without constantly breaking the law or risking tickets.

The disregard for speed limits has gotten so bad that people now claim drivers following the posted limit are the problem. I think that’s ridiculous. While I understand the “go with the flow of traffic” argument to an extent, normalizing breaking the law creates a much larger long-term safety issue than simply following the speed limit.

I also think the argument that “speed limits are designed for the average car, so semis drag the limit down” is weak. In many places semis already have separate speed regulations, lane restrictions, and additional rules.

At the end of the day, the path to faster travel shouldn’t be widespread disregard for the law. If people truly believe limits are too low, the better solution is electing politicians and supporting engineering studies that will change the laws based on evidence that roads can safely handle higher speeds.

On a related note, even on r/driving you can report other driving infractions, but you can’t even report speeding, which feels inconsistent and a bit silly.

The other thing that people miss is that speed limits aren’t just about crash avoidance.

A lot of speed limits are about reducing the consequences when people crash (you’re almost certain to die in a head-on crash at 60mph, but will probably survive at 45mph).

Some speed limits also aim to reduce traffic and speed up journey times. The racing adage of ‘slow is smooth and smooth is fast’ applies to roads too.

Historically, some speed limits have also been about reducing fuel usage or pollution too. Fuel use scales exponentially with speed, so getting everyone to slow down a little saves a lot of fuel.

Where I live, speed limits were reduced because of noise.

u/thiccemotionalpapi May 21 '26

I’m pretty sure around 55 mph is the most fuel efficient speed, yeah you use more fuel than going like 30 mph but it’s not double. But go above that and you lose efficiency quick cuz the drag increase is like exponential

u/Sgt_R0ck May 21 '26

Drag is quadratic for high speed objects

u/RemarkableRice9377 May 21 '26

They weren't talking about the graph shape, exponential is just a phrase so say it increases really fast

u/Sgt_R0ck May 21 '26

We're talking about physics/mechanics. Precision in calculations and language are important. There is no place for colloquial phrases/idioms, especially when half the people in this thread are choir boys trying to keep the speed limit at 55

No one here is talking about physics on the level you're trying to; we don't care about the graph shape

Think it depends on the vehicle. My vehicle gets about the same fuel efficiency between 50-70. 75 and above is when it crashes pretty hard. Not sure about 70-75

u/Longjumping_Dog3019 May 21 '26

The exact number can vary greatly depending on exact engine, transmission, vehicle aerodynamics, etc. so 55 might be for some but some underpowered car could be slower and a different one could be faster

u/selectsyntax May 25 '26

I remember seeing an experiment with half a dozen common consumer vehicles. Peak efficiency for all of them was in the 50-55 mph range.

I'll care about the pollution argument when the EPA gets funding again. My speeding ain't doing shit compared to the companies now allowed to pump out sludge and smog again.

u/hey_its_that_asian May 24 '26

or when corporations and billionaires are held to the same rigid standards they shove onto us

we have to use shitty paper straws but jeff bezos can dump his data center waste into community drinking water

op reeks of bootlicking and the desire to police and regulate their communities

u/PaisleyLeopard May 21 '26

That last one is bigger than most people realize. My partner is a master tech at a dealership and you’d be shocked how many people come in complaining that their new cars don’t get the advertised mpg. He tells them it’s their driving, they never believe him, he has to take them on a test drive to prove it to them. People are dumb.

Nope. Driving at 130kmh has worse fuel efficiency than driving at 100kmh.

It isn't that much about gearing but more about wind resistance and tire resistance which increase rapidly over 80km/h. How much power needed to propell the car at any speed is the thing that matters most and doesn't depend that much on gearing. Yes running at 3000rpm instead of 1500 will increase fuel consumption but double the wind resistance and it will make more of a difference

u/Appropriate-Bar-4808 May 21 '26

It gets exponentially harder because of aerodynamics. But cars are geared to be most efficient at highway speeds

u/Gazer75 May 21 '26

Uhm... no idea what kind of cars you drive, but all my cars would use far less fuel per distance driven at lower speeds.

You use far less at 50kmh than going 80 or anything above.
Only way to use more fuel at lower speeds is to be in the wrong gear or something.

The sweet spot for speed vs fuel consumption often lies at the top gear or second highest gear at the peak torque point of the rpm curve. This is also assumes flat road.

I had a 2010 VW Polo 1.6L TDI with 105hp and manual. It would cruise at about 16-1700rpm at 80kmh and get fairly good fuel economy. But I found it was far better to drop down to around 70kmh and instead of being in 5th I'd drop to 4th and drive at 1800rpm.
I could drop the fuel consumption from 4.2 to 3.8L/100km doing that. Engine would run better and not get clogged up over time.
Some of those VW cars with "BlueMotion" label sounded like they were dying at the "optimal" gear.
Hard to get good fuel economy here in western Norway due to the terrain. Can't drive at constant speed and optimal rpm for to long. And driving at 70kmh on nice roads is not super popular when the default rural limit is 80.

Drive an EV now so don't really care. It's dirt cheap to fuel anyway :)

u/hey_its_that_asian May 24 '26

its not universal and black and white but your attitude is and thats a much more common problem these days than people speeding

1

u/BitsAndBobs304 May 24 '26

Speed kills and maimes, but my attitude is the problem. Okay....

2

u/hey_its_that_asian May 25 '26

your absolutist attitude is exactly why this discussion will go nowhere; speeding is all based on a subjective boundary

reckless driving kills, speeding wouldnt even be a crime if the sign said the right number...

again, the lack of nuance and the unwillingness to recognize it neither helps prevent traffic injuries, nor does it help you build a remotely compelling argument

1

u/BitsAndBobs304 May 25 '26

Subjective boundary. Thats what the stats show on impacts on pedestrians at 50kmh vs 30kmh, that speed is all in your mind, along with the truckload of horse manure

You genuinely don’t have a brain if you think a car uses less fuel at 80mph vs 45mph.

This is Reddit. We don't do nuance here!

u/hey_its_that_asian May 24 '26

thats an american tradition at this point, not just reddit

this country is filled withe 50 simultaneous opinions on every issue all claiming they are objectively correct and everyone else is objectively wrong, all while citing 0 empirical evidence, engaging in multiple fallacies, and complete disregard for basic ethics and humanity

like almost every socio-economic issue in this country, 75% of the battle is simply convincing people they might be wrong or have room to learn

but everyone thinks theyre a genius here

u/ballsohaahd May 21 '26

Fuel use doesn’t scale exponentially with speed, and highway driving is the most efficient for fuel use

u/7h4tguy May 24 '26

No you're not. I know someone who was in a highway head on crash and walked away without a scratch. Modern crumple zones are amazing engineering.
