Let’s just say that am Airbus A320 takes off at around 270 km/h.
So having the aerodynamics you can literally fly at that speed. Well, weighing more than 37 tons, even.

You can at much, much slower speeds. For example this STOL plane only stalls at 32km/h).
Strider@lemmy.world 1 year ago
Indeed, that’s why I added the (empty, so even more than) 37 tons weight.
CLOTHESPlN@lemmy.world 1 year ago
Realistically you don’t get to react at that speed. Best you can do is slow down and hope… Anything more than small adjustment of the steering wheel and you’re no longer on the road. If I crashed at even half that speed I would probably wish I was dead because it’s going to be a very long time if ever I function correctly again.

We traveled to Germany years ago, rented a car and drove on the autobahn with no speed limit. We were on a long down hill in a brand new audi a6 … beautiful car and I floored it in the passing lane to 260 kmh … I was scared shitless because I knew that all I needed was a rock on the road or a little bump and we’d both be dead. I looked in my rear view mirror and a guy was flashing me from behind. He wanted me to move over and he passed us just seemingly floating right past us in a luxury Mercedes.
That was the fastest I’ve ever driven anything and it was scary. The car was fine, it’s just knowing that if any small thing came in our way at that speed, the car would fly, crash, crush us to death, rip apart and blow up in a blaze of glory. You can survive a crash at 140 kmh … it would be a miracle to have your body remain in one piece in a crash at 300 kmh

You technically can survive a 140kph crash in the same way that technically you can survive jumping out an airplane at 10 kilometers, or how you can survive rabies
Technically possible as there are few recorded incidents, but let’s say that you easier win the lottery than surviving any of that shit.
Was it myth busters who smashed a car against a wall at 120 or 140 kph? Don’t know anymore but I do recall the car literally being folded up
At those speeds, crumplezones extend way into the back of your head, so again, you can quite safely bet you’ll die.

I find it weird that a rental wasn’t limited to 250 km/h. Which most factories do by default. In fact it should be limited to even lower than that IMO.
x00z@lemmy.world 1 year ago
Why should it be if it’s not illegal to go vroom vroom? Makes no sense.
Tja@programming.dev 1 year ago
It probably was indicated 260, real 250. Even the S6 is limited, and for the RS6 you have to buy an option to rise the limit.
ininewcrow@lemmy.ca 1 year ago
I don’t know honestly … all I know is that the A6 had about 5,000 km on the odometer and everything was pristine new … it was the most luxury brand new car I ever drove. We had to haggle the rental guy to upgrade our rental from a standard rental to one size up … he didn’t have anything in our range but said that he would look into upgrading us further and we ended up with the A6.
Like I said, we were on a nice long downslope in the country side. It was easy to floor it and build up speed but the car seemed to max out at 255 260 and I couldn’t get it any further. The best part was that Mercedes flashing us from behind and wanting to pass.
Later on on the same trip, we noticed to helicopter flights overhead carrying cars away from an accident … they don’t seem to bother calling in tow trucks to carry things away because the pieces of cars that are left from a high speed crash are small enough to be carried away with a chopper.

That’s an American law, so vehicles weren’t faster than police vehicles, there was ways to remove the governor though.

300 kph is 186 mph, which is well beyond the posted speed limit of any jurisdiction I can think of. For reference, here in California, a conviction for driving over 160 kph (100 mph) is punishable as a felony, meaning at least one year in state prison. The highest speed limit in California is 113 kph (75 mph).
In metric units, a triple digit speed (eg 100 kph) is the domain of motorways (aka freeways or expressways). And even arrow-straight motorways have a maximum posted speed limit of some 140 kph. In Germany, the motorway can sometimes have no limit, but the recommended speed – the yellow speed limits in the USA – for German autobahns is 130 kph, with some speedy cars occasionally doing 200 kph, I’ve heard.
For further reference, the fastest speed achieved during an F1 motor race is 372 kph. Also, Japanese bullet trains heading west from Tokyo on the Tokaido Shinkansen route run at 285 kph.
300 kph on a public road is grossly irresponsible, since even with no one around, the road is not designed for that speed. Compare race tracks with freeways, and it becomes clear that surface quality, drainage, sight lines, clear space, and other requirements for 200+ kph just aren’t present on public roads, with the notable exception of very special public roads like the Nürburgring.

The fastest I drove was 262 km/h on the German highway (which has sections without a speed limit). At this speed, you have to watch as far as you can, because a car on the left lane overtaking other lanes will usually be at most 180 km/h there, so you have to be prepared to slow down a very long time in advance.
300 km/h is just dangerous, you have to be fully concentrated to adapt to the other drivers and it leaves a very thin margin to react (if any), should something happen. You definitely put your life and the one from others around you one the line doing that.
My experience wasn’t particularly pleasant, but it was nice to feel once how the car behaves at its maximum rated speed. I haven’t done it again. But I’ll regularly drive above 160 km/h to just go with the flow.

It’s about 3 times the speed limit for most highways in most places. Give or take.
The stopping distance at those speeds is 500+ meters.
Even with the best tires, brakes and driver that’s several football fields end to end before that car comes to a stop. If anything happens at those speeds it is unlikely the driver will be able to do anything about it in time.
There was a woman that worked for a car magazine that was doing a video on the Autobahn and someone pulled out in front of her around those speeds she instantly killed everyone on the vehicle she hit and she was left permanently injured and barely able to walk. She wasn’t even at fault in that situation either. It’s the job of the people pulling into the fast lane to check for fast moving cars and for whatever reason they didn’t.
You friend is playing a dangerous game with more than their own life.
LazyGit@feddit.org 1 year ago
If you go faster than 130 km/h you are always allotted a certain percentage of fault in Germany. You don’t have the right to speed if you are endangering others.
MoreFPSmorebetter@lemmy.zip 1 year ago
That is simply not true. 130kph is the recommended speed. For certain marked stretches of the Autobahn there is no speed limit and it is understood that you do not pull into the left lane without checking for fast moving cars behind you. If they find that you still would have crashed if you had been going 130kph you are unlikely to be held responsible.
She was filming a video at the time and when she woke up in the hospital days later the German police told her what had happened and she was not found to be at fault at all. The deceased person who had pulled into the left lane without checking was entirely at fault. She flew home as soon as the German doctors had done the major surgery to her legs and spine.
My mom’s entire side of the family is German and many of them still live in Germany. Talks about the Autobahn have come up at family gatherings on multiple occasions.
I am willing to admit my data might be out of date, but from a quick Google it appears to still be the same rules.
Takapapatapaka@lemmy.world 1 year ago
Well it depends. Technically speaking, it’s around twice as fast as standard speed on highway (at least in France, so 130kmh). In terms of feelings, it’s probably not that faster? I never went above 140 or so but from my experience, your brain adapts to the speed, so if you got to 300 not that suddenly it probably does not feel like twice as fast than the usual. In terms of safety, it may be more than twice the danger. I’m no expert, but depending on the vehicle and how many other vehicles there are on the highway, it could be very dangerous.
WoodScientist@sh.itjust.works 1 year ago
That’s 186 mph. In the US, the highest posted speed limit anywhere is 85 mph, on some stretches of highway in remote rural Texas. So you’re looking at more than 2x the speed limit of the highest posted speed limit in the country. A lot of cars come preprogrammed with some speed governor in them. They usually top out at an already absurd speed of 125-155 mph.
So 300 km/hr is absolutely insane. That’s enough to get jail time in most states.
kitnaht@lemmy.world 1 year ago
That’s about 40mph faster than I’ve ever driven, and even in a sports car it gets squirrely VERY fast at those speeds. Holy shit.
WoodScientist@sh.itjust.works 1 year ago
Oh, and for added physics fun, that extra 40 mph represents a 62% increase in vehicle kinetic energy and stopping distance.
nesc@lemmy.cafe 1 year ago
Almost two times faster that is safish to drive.
PonyOfWar@pawb.social 1 year ago
Ridiculously fast. More than double than what most people will drive on a highway. Illegal on a highway anywhere but Germany. And even here it would be quite unsafe and thus illegal in most driving conditions.
onehundred@lemm.ee 1 year ago
186 miles per hour. It’s fast, really fast, Depending on country likely really illegal
IDKWhatUsernametoPutHereLolol@lemmy.dbzer0.com 1 year ago
If your friend perhaps a German?
(I heard they have no speed limits 👀)
MemmingenFan923@feddit.org 1 year ago
This is half true. Some highway segments have speed limits like everywher else and some don’t have speed limits.
SomeAmateur@sh.itjust.works 1 year ago
And that system is AWESOME and I wish some highways in the US did the same. I fear it would devolve into a regulations nightmare after bubba in his rusted dodge rattles to peices trying to break 80mph.
Flat open highway in between cities in Kansas? Go for it!
But it’s kind of like the US and guns. It’s a cultural ability that is statistically proven to be dangerous and can be seen as too big of a risk for ordinary people to enjoy, and reckless people put the whole acrivity in question.
