On a highway you would usually go 80-120 kmh.
No easy way to imagine that kind of speed in a car for most people.
Here are some things and their speeds in kmh:
- human falling at terminal velocity belly down: 200 kmh
- plane right before touchdown: 250 kmh
- f1 racer: 320 kmh
- cannon ball being fired: 3000 kmh
- fastest baseball pitch: 170 kmh
Anyway, he probably has only a few more times of that before he crashes and instantly dies (and probably kills a bunch of people)

In moon landing units that’s ~186 miles per hour, which is around three times the speed limit of an average American interstate highway. I would not expect the average passenger car to be able to achieve that speed, but there are sports cars that can. You’re probably looking at an uprange Corvette, some of the higher end Porches, a lot of Ferraris, Lambroghinis etc. Something Jeremy Clarkson would describe in an impressed tone of voice. It is my understanding that a lot of supersport motorcycles are limited to exactly that speed; most liter bikes have no problem powering themselves that fast, the question is maintaining control. If there’s a pothole or some sand or a slight curve, will the rider survive encountering it at 3 miles a minute?
Going that fast in a car, you start to wonder how long the tires are going to hold up. At its top speed, a Bugatti Veyron will actually run out of tires before it runs out of gas.
In New World landing units, it’s ~161 knots. This is very close to the V~NE~ of a Cessna 172 Skyhawk. The Never Exceed speed, top of the red arc. Go faster than that and the airplane is just going to break. It’s the approximate cruise speed of a Beechcraft Bonanza and the higher end of landing speeds for a Boeing 737.

Don’t think they did, I’ve had some high performance cars and it takes time to get up to speed, need flat road and at that speed any other car is going to likely lead to a crash.
Most cars don’t even have the right gears to get to that speed, so I call BS.
M3 top speed is 250 Porsche 911 is 330
It would take well over 10 seconds to get to that speed in a supercar, and impossible in a normal car.
Sylvartas@lemmy.dbzer0.com 1 year ago
That is almost 3 times the highway speed limit and roughly 83 m/s if I got the math right. At that speed the car will travel 40m on average before you even press the brake pedal, then the average car will take probably about 1s (which I think is conservatively low) of emergency braking to stop (or almost), traveling another 83m.
bstix@feddit.dk 1 year ago
Unpredictable things happens at that speed.
Forget about braking distance. The reaction time is the difference between life and dying before you even know it.
I know of one example where a motorcyclist killed himself that way. Nobody knows how fast he was going but it’s assumed above 250 km/h, on a regular highway. Down the road is a cross section. A lorry was fully stopped at the crossing and preparing to turn right onto the highway in the same direction as the motorcycle. The lorry driver checked both directions and saw that the road was completely clear as far as the eye could see, hundreds of meters.
A split second later he heard a bump and pulled over to check if he had hit an animal or something. He found a massive hole in the back and the debris from a motorcycle. There was no brake marks or anything indicating that the motorcycle had even attempted to brake or steer around. The theory is that the motorcyclist might have glimpsed at the speedometer or something for long enough that he drove the entire visible distance before being able to even react.
Obviously he was a fault himself, but the point is that at speeds like this, you no longer have any capability to predict what happens next.
If your friend thinks that cool, he might as well play Russian roulette. At least that doesn’t put innocent people in danger.

Just the right speed for high-speed trains.
Allero@lemmy.today 1 year ago
This is basically Formula-1 race car/small aircraft speed.
Regular cars will only get you to, like, 160-180 km/h at full gas.
In other words, this is insanely fast and potentially very deadly.
At speeds above ~150 km/h, even on a well-organized highway, you won’t be able to control your surroundings and have to rely on sheer luck to survive, unless you’re a professional race pilot on an empty road. Also, unless the car is equipped with special gear for improved road grip, it will become uncontrollable because it will literally start to hover a little.

sorry but no. maybe i am biased since my sole experience is driving the german autobahn, but i drive well beyond 200km/h on a regular basis, which i consider travel speed when the road is not too crowded. cars that could go faster than 250km/h are usually limited to 250km/h. traveling at that speed is loud and a bit stressful, since the difference between you and other cars traveling at lower speeds becomes too high. they will not see you coming before switching lanes and braking distances are very high. but cars dont randomly switch lanes unless tying to pass others cars and you can predict these situations and slow down.
you will not hover, you can control your car normally and the only required luck is to not have other actively try to kill themselfes. you dont need to be a professional race pilot and dont need special gear (of course cars can easily be underequipped for these speeds, but you dont need special gears.
do you mean speeds above 250km/h or speeds above 150mp/h? if that was just a typo i would argue a lot less because those speeds stop being fun to drive, but are also accessible for normal drivers with normal street cars (with enough power of course, but you see plenty of those cards on the average parking lot in front of any supermarket)
oascany@lemmy.world 1 year ago
I agree 300 km/h is insanely fast and stupid on public roads.
The rest of your points sound like you live in 2005.
A lot of regular traffic nowadays will get you to 200 km/h. Above 150 km/h is not relying on sheer luck, I’m sorry that’s just not true. Yes it’s really really fast and really illegal, but you maintain control given a few conditions.
I’m also not sure what you mean by “special gear for improved road grip.” A car’s shape naturally somewhat resembles an aerofoil, so yes you generate lift at high speeds. Most modern cars account for this by aerodynamic design, including but not limited to things like diffusers, spoilers, splitters, and the shape of the body itself. These help keep you planted along with good suspension and good tires. I’m certain that just about any car made within the last two decades will not become uncontrollable past 150 km/h unless you’re driving on a really wet surface.
ColdWater@lemmy.ca 1 year ago
You die 3x faster than 100km/h if you crash
Gobbel2000@programming.dev 1 year ago
Maybe 3x faster, but because Energy = mass × speed SQUARED, you die 9x harder.
whaleross@lemmy.world 1 year ago
You also risk killing x3 more innocent bystanders.
Don’t play with motor vehicles on public roads or whatever happens is not an accident.
zxqwas@lemmy.world 1 year ago
About three times the usual speed on a highway.
And a highway is about three times the allowed speed of a school zone.
So roughly the same as driving highway speeds in a school zone.
Krudler@lemmy.world 1 year ago
I really don’t know what you’re looking for here. I mean what do you want us to say It’s a speed??
I guess if I can add something meaningful, it’s so fast that no human can ever respond to an unexpected situation or hazard in time and you’re dead. Don’t ever go that speed for any reason.
Agent641@lemmy.world 1 year ago
About three times the speed limit of freeways in Australia.
About the same as the top speed of a Honda CBR-XX Blackbird, which at production in 1998 was the fastest production bike in the world.
gazter@aussie.zone 1 year ago
Formula 1 races average about 200kph, with a top speed of 375. These are the best of the best professionally trained drivers in multimillion dollar equipment tailored to them and designed to keep them (and others) safe at those speeds.
300km/h on the highway is essentially suicide by stupidity, not to mention manslaughter for whoever you hit. You are travelling fast enough that you literally don’t have time to react to something several hundred metres in front of you.
150 is really fast, 200 is stupid fast, and 300 is really fucking stupid fast.
Opinionhaver@feddit.uk 1 year ago
Fastes I’ve driven was 200km/h and it felt like if I’d hit a pebble my car would’ve taken off. 300km/h is airplane speed.
TheRealKuni@midwest.social 1 year ago
Yeah, in my younger days I got up to ≈210km/h once. I can’t believe I was dumb enough to do that.
At 200km/h, you’re passing the cars around you as quickly as you usually pass stuff stationary by the side of the road. It’s insane.
The car felt planted and controlled, but still. One slightly wrong move and I would’ve been flying off an embankment or killing a fellow motorist.
Opinionhaver@feddit.uk 1 year ago
Doing it on empty highway at the middle of the night was scary enough for me.
x00z@lemmy.world 1 year ago
It really depends on the car. Newer cars and better brands will make 200km/h feel like 100km/h.
I have driven a car from 2000 that would completely start rumbling at 160kmh, compared to a car from 2022 where 220km/h felt like I was driving on clouds.
Opinionhaver@feddit.uk 1 year ago
Yeah, the first time I tired it I got to 160kph on a -03 hatchback Corolla and it felt like the mirrors were about to fly off. The 200kph I did few years later was on a -01 Audi A6 and the ride was smooth as hell and the car felt very planted. It’s just that at those speeds even low bumps feel like ramps.
zakobjoa@lemmy.world 1 year ago
I got my 1996 Renault Laguna up to 200km/h and it felt and sounded like the engine block was about to jump into the passenger cabin.
slaneesh_is_right@lemmy.org 1 year ago
My first nice car was a bmw from 2008, and driving through germany was definitely an experience. 260km/h felt like 120km/h in my first car.
trolololol@lemmy.world 1 year ago
My car rumbles at 100km/h and it’s a 2016 model. It’s just cheap, what do you expect?
zeropublix@lemmy.ml 1 year ago
That’s so true. Drove my fiat panda with 180 (dunno how I got it there. It was downhill for sure) and it was absolutely terrifying.
Later drove an Audi A6 with 230. Obviously fast but nowhere near terrifying.
Another time a company Ford Mondeo (Diesel) 240 and it felt like sitting in a train.
I want to stress that I never kept those speeds for long. It was rather seeing how fast I can go in a setting that allowed it with minimal risk for everyone involved. I must say that I don’t see the thrill in driving that fast. Everything is so exhausting to pay attention to.
TheCriticalMember@aussie.zone 1 year ago
3 times as fast as 100? I don’t know what you’re expecting here. It’s 83.3 metres per second, if that helps. Your friend must have a nice car, there’s not many that can go that fast, and even fewer that can do it and still handle predictably.
Tungsten5@lemm.ee 1 year ago
That is very fast. So fast in fact that at in only 1 hour you will travel 300km.
RaptorBenn@lemmy.zip 1 year ago
Faster than I’d trust a goverment built road is flat.
AnAustralianPhotographer@lemmy.world 1 year ago
Ridiculously fast.
Bullet train fast. But in terms of cars, he would have been driving around three times the legal limit in Australia (110km/hr). Its about as fast a formula 1 cars or out V8 cars going full speed.
The fastest production car (Bugatti Veyron can go 431km/h)
Mothra@mander.xyz 1 year ago
Okay so I don’t know if you’re into birdwatching at at all but that’s about the top speed of a peregrine falcon. Have you ever seen a bird of prey dive to attack?
That’s also about the stalling speed of a passenger airplane, that is, the minimum speed it must fly at before losing lift.
I couldn’t think of anything else that goes at around 300kmh but if I get new ideas I’ll let you know.
Mac@mander.xyz 1 year ago
That’s unreasonably fast even for car enthusiasts.
The percentage of consumer cars that can even do that is infinitesimally small.
DozensOfDonner@mander.xyz 1 year ago
I doubt typical commercials available cars can do that speed, maybe some super expensive stuff? I’ve never be driven a car which could top over 180.
hemko@lemmy.dbzer0.com 1 year ago
~83m/s
For the Americans here, 83m is ~0.83 football fields
It’s more than 3 times the common speed limits on roads, and more than 2 times faster than any speed limit on a motorway in the world (Autobahn doesn’t have limit)
Let’s imagine your car could pull 6g while decelerating, which is the upper limit what non-trained person is able to take. This would mean that from hitting the brake pedal, your car would move for another 1.4 seconds, in which time it had moved 116 metres. Realistically it’d be A LOT longer but should give a some kind of idea
otter@lemmy.ca 1 year ago
This is something that’s hard to describe with words
This video has someone going that speed, they also talk through some of the considerations on how to do that safely
4K HDR POV: How to drive 300+ kmh on German Autobahn in a McLaren
There’s also this video with a motorcycle doing something similar
foggy@lemmy.world 1 year ago
You can use Fibonacci to approx km/mi
300 km is like 200 mi.
(More like 180)
But still, approx works. 300 kmh is like 200 mph. Closer to 180 mph.
Buffalox@lemmy.world 1 year ago
It’s way faster than most cars can drive. Even high end performance cars often have a limiter at 250 km/h.
Here in Denmark, the limit is 130 km/h, If you drive 200 or faster, your car is immediately confiscated, and you lose your drivers license.
Many electric cars are limited to 160 km/h.So in short 300 is about twice what most would consider responsible. The breaking distance is 550 meter or more than half a km, in ideal weather with no slopes, and a response time to push the brakes of only half a second. That’s almost 5 times the breaking distance compared to driving 130 km/h (113 m).
Just in the half second to respond, the car will have moved 42 meters at 300 km/h!!SomeAmateur@sh.itjust.works 1 year ago
That is the kind of speed it takes to get a 747 into the air on takeoff.
If you rolled down a back window of a car and stuck your head out (not recommended) you would feel wind that would max out typhoon and hurricane scales, similar to an EF4 Tornado. The skin of your face would flap like fabric, as seen here

BOFH666@lemmy.world 1 year ago
It is ridiculous fast and probably not really smart.
But, the fact that we (Europe) have labels for the maximum speed a tire is approved for even till 300kmh, does indicate it is not abnormal.
As others already mentioned, above a certain speed, in case of an accident, you will be held more accountable.
But folks with BMW, Audi, Porsches etc. do drive serious cars. Going faster than 250 is not an issue with most of the models. The biggest challenge is to slow down from these speeds in a controlled way.
Onomatopoeia@lemmy.cafe 1 year ago
It’s abnormal.
That kind of speed requires 500hp+, depending on Cd and frontal area.
What percentage of cars produce 500hp?
(Im not even sure 500hp is enough, it’s been a while since I’ve done the math).
Small increments in speed require non-linear increases in power.
spittingimage@lemmy.world 1 year ago
About twice as fast as my car is capable of going, downhill and with a tailwind.
Treczoks@lemmy.world 1 year ago
I rode a train going 300km/h, and it felt amazingly slow, compared to going 180km/h on the Autobahn in a car.
