Not 10% but 10kmh. That's a big difference. At higher speeds it gets more accurate. Examples, real VS speedometer (off %): 20kmh = 10kmh (50%) 100kmh=90kmh (10%) 200kmh=190kmh(5%) 300kmh=290kmh(2%)
Nope, the speedometer is usually tuned to be the most precise at 50km/h for inner city driving. I only know of the Alfa Romeo Giulia with the Quadrofoglio which has its speedometer tuned to high speeds but warns to this in the manual. When I drive 107 km/h, GPS shows 100, at 200 GPS says 189 km/h; and it is definitely correct because that is the rev limiter (and I ride the stock rims with same dimensions from factory).

Theres something called cosine effect when it comes to speed radars. Basic principle it works on is by measuring distance change over time. It's programmed to measure distance from the back or front of the vehicle so every other angle you measure it from, will greatly effect the result. If you tried to measure speed from the far side it would show even smaller numbers.
Close, the radar uses the doppler effect, this only gives you the radial velocity, which is the velocity along the line of sight of the radar gun. The car isn't travelling along the radar gun line of sight, hence the discrepancy.
If the Golf has the standard tune on it (235hp), then it would be more surprising if it really managed to reach real 260 km/h. Because of the tuning rims, the speedometer shows more than the actual speed. In Germany (where the Video was Made) it's allowed that the speedometer shows 7% more, which means, that he's driving at around 242 - 245km/h
Probably gearing. 100HP cars here can hot 200km/h as well. So with double the power and a long enough time it might be possible. Could be still tuned though.

I can guarantee 10% (the max value) is not applied at any vehicle ive driven so far. At my Audi (Belongs to Volkswagen) I was once meassured at 140km/h while my Speedmeter in the car indicated 141. So this calculation does not matter at all

The problem with radar is the walls on either side and the only way to use that gun is without any other wall or vehicle for the radar wave particle to bounce off if.
This would have very small effect. The bigest reason is that he is measuring at an angle and therefore the device is not showing the total velocity but its projection into the direction of radar v*cos(θ), where v is total velocity and θ is the angle from horizontal axis parallel to the ground.
Depends on if it’s a licensed and checked radar device. If it’s a aliexpress thing sure it’s not working properly. But usually a difference of 20 kp/h is normal with those speeds
Also, car speedos usually read slightly higher than irl speeds to be safe, like 1-5mph. So the actual speed it prolly around 1-5mpg slower than what the tach says.
Yeah I've heard that the speedometer in cars tends to read high, and the reason I've heard is to keep people at reasonable speeds, since everyone goes over the limit by at least a little. For example when the speed limit is 35 and people tend to go 10 over, when their speedometer reads 45 they are actually only going 40.
Both the instrument and the car speedometer are perfect. The difference is caused by the mistake made during using the radar. The line of measurement and the path of the car are not parallel, there is a significant angle between them. The radar is measuring the velocity component in its line and this is less than the total velocity.
You guys got a good point about the angle that theyre reading the car from and it has to be head on, but im pretty sure thats a baseball gun btw atleast thats what I've seen that brand used for.
This model works both ways. But is only accurate if you re perfectly head on to the target. The cosine effect would result in an under reading of the speed of the target.
90% of 260 indicated speed is 236 of real speed 85% of 260 iindicated is 225 of real speed Every car since 2003 year must have 5-15% overshoot when stock
The overshoot gets smaller the faster the car gets, the issue is the degree he is aiming from the bridge. Assuming the overshoot is 5% according to physics he should be holding the pistol around 29° relative to the movement direction of the car. Vm= V0*cos(x) or V0*distance_h/(distance_h^2+distance_v^2)^0.5 where V0 is the speed of the car, x is the angle, distance_h is the horizontal distance and distance_v is the vertical distance
Car speedometers read higher than their actual speed. Mine reads 10% higher than the GPS speed on my phone. 260kmh on the speedometer would be around 236kmh if the speedo is 10% biased
Die maximal erlaubte Abweichung vom Tacho sind 10% + 4 km/h. Bei Tacho 260 km/h wären das real mindestens 232,7 km/h. In der Regel ist die Abweichung jedoch deutlich geringer (ca. 5% würde ich noch für realistisch halten, meist sogar weniger). In jedem Fall ist das Messgerät falsch. T = Tacho R = Real 1,1*R+4=T R=(T-4)/1,1 für T=260 ergibt R=(260-4)/1,1=232,7... Achja, auch mit fast über 200 km/h gilt noch das Rechtsfahrgebot.
Noch ein paar Ergänzungen: Die Toleranz ist ein Maximalwert und gilt nur nach oben. Der Tacho darf nie zu wenig anzeigen! Der Tacho geht in Wirklichkeit extrem genau, muss aber vom Hersteller auf den Worst Case abgestimmt werden. Worst Case ist der größt mögliche Reifenumfang, weil damit bei gleicher Drehzahl und Übersetzung die höchste Geschwindigkeit erreicht wird. Der Tacho ist also notgedrungen so abgestimmt, dass er mit den Reifen vom zugelassenen Hersteller mit dem größten Umfang, dem höchsten Profil, höchstem Luftdruck und höchsten Fliehkräften immer noch mindestens die reale Geschwindigkeit des Fahrzeugs anzeigt. --> Daher ergibt sich zwangsweise die Abweichung nach oben im "Alltagseinsatz". Die Anzeige des Messgeräts scheint aber vollkommen korrekt für den Winkel in dem gemessen wird...
Thats because every german knows the GTI cant drive more than 250kph... Depending on wheels and tires the speedometer will Show +10-20 kph more than GPS. Try with Google Maps.
Dunno bout in Germany but in the UK, Speedo’s are set to about 15% less when going 100mph (161kmh), meaning when doing 100, you’re actually closer to 85mph. This would mean that at 260kmh on the Speedo, or 160ish mph, you’d actually be doing closer to 220kmh (130ish mph), which means this is an accurate gun.
In Germany the tachometers in cars show always a 110 % of the speed you actually drive So if your tachometer says 110 you actually drive 100 If his car says 260 you have to subtract at least 26 kmh In German driving schools you learn formulas for your breaking distances and to keep people out of trouble there are hidden securnesses
I can drive with 58 kmh trough a speed camera at a given limit of 50 5 kmh because my tachometer is 10 % off and 3 kmh because the law gives you +- 3 kmh for the inaccuracies of the speed camera Don’t test it
A police officer actually said something like this, that the speed they book you a ticket for isn’t actually your actual speed they book you for about 10-20% less of the speed you were actually going at, that’s why if they stop you for speeding you were definitely speeding.
Um where. All my speedmeters on my cars are correct and match my gps unless your talking about going fast like in the 150mph + range but that could be multiple different things as to why its off, Worn tires, wrong size tires, your differential, etc.
And here I am in Australia being told that going 101kmh will instantly kill an entire family... Lack of lane discipline and consideration of the drivers around you is what's killing families!

I got challan for driving on 80+ speed
no europe have smalll roads 90% of the time 😢 😑 😒 😕 🙄😞 😢 😑

What happened to 120 kmph? I thought it was 120
Car speedometers are known to read over gps speed
Yeah they have an inaccuracy of 10%
Yeah, but not 50 kph difference to real speed.
Not all speedometers. Not all vehicles have on-board GPS
244,4 actual speed - angle = pretty accurate radar
This is what happens when you don't know physics.
90% of 260 indicated speed is 236 of real speed
85% of 260 iindicated is 225 of real speed
Every car since 2003 year must have 5-15% overshoot when stock
The overshoot gets smaller the faster the car gets, the issue is the degree he is aiming from the bridge. Assuming the overshoot is 5% according to physics he should be holding the pistol around 29° relative to the movement direction of the car.
Vm= V0*cos(x) or V0*distance_h/(distance_h^2+distance_v^2)^0.5
where V0 is the speed of the car, x is the angle, distance_h is the horizontal distance and distance_v is the vertical distance
@@pyromanga actuallly the overshoot gets larger. At 132kph indicated I was driving 128kph GPS, at 260 indicated, I was driving 239 GPS
@@pyromangahow would that make sense? if you were to go from 0 to 10 kph, would it show that you're going something like 20 or what?
Car speedometers read higher than their actual speed. Mine reads 10% higher than the GPS speed on my phone. 260kmh on the speedometer would be around 236kmh if the speedo is 10% biased
Yes, but only for German Cars Build in Germany. US Cars' shows the Real Speed.
@@v8guru402you can vary your speed just by switching to different size tires.
Absolutely love the effort to put in the censor so we would need to watch the entire thing to know it's speed 😂

die Geschwindigkeit auf dem Tacho ist nicht akkurat nimm mal n gescheites GPS im Auto und Teste damit nochmal
Die maximal erlaubte Abweichung vom Tacho sind 10% + 4 km/h.
Bei Tacho 260 km/h wären das real mindestens 232,7 km/h. In der Regel ist die Abweichung jedoch deutlich geringer (ca. 5% würde ich noch für realistisch halten, meist sogar weniger). In jedem Fall ist das Messgerät falsch.
T = Tacho
R = Real
1,1*R+4=T
R=(T-4)/1,1
für T=260 ergibt R=(260-4)/1,1=232,7...
Achja, auch mit fast über 200 km/h gilt noch das Rechtsfahrgebot.
Also the angle of the laser beam, is at and Angle, which decreased the speed displayed.
Noch ein paar Ergänzungen:
Die Toleranz ist ein Maximalwert und gilt nur nach oben. Der Tacho darf nie zu wenig anzeigen!
Der Tacho geht in Wirklichkeit extrem genau, muss aber vom Hersteller auf den Worst Case abgestimmt werden.
Worst Case ist der größt mögliche Reifenumfang, weil damit bei gleicher Drehzahl und Übersetzung die höchste Geschwindigkeit erreicht wird.
Der Tacho ist also notgedrungen so abgestimmt, dass er mit den Reifen vom zugelassenen Hersteller mit dem größten Umfang, dem höchsten Profil, höchstem Luftdruck und höchsten Fliehkräften immer noch mindestens die reale Geschwindigkeit des Fahrzeugs anzeigt.
--> Daher ergibt sich zwangsweise die Abweichung nach oben im "Alltagseinsatz".
Die Anzeige des Messgeräts scheint aber vollkommen korrekt für den Winkel in dem gemessen wird...
Thats because every german knows the GTI cant drive more than 250kph... Depending on wheels and tires the speedometer will Show +10-20 kph more than GPS. Try with Google Maps.
Also most cars show about 10% more speed over the real speed so 10% out of 250 would be 25
Speedometers in cars always shows more than the actual speed in order to reduce speeding. So probably Spot on
Dunno bout in Germany but in the UK, Speedo’s are set to about 15% less when going 100mph (161kmh), meaning when doing 100, you’re actually closer to 85mph. This would mean that at 260kmh on the Speedo, or 160ish mph, you’d actually be doing closer to 220kmh (130ish mph), which means this is an accurate gun.
380 км/ч мимо тещи
Speedmeters usually show 4-8 kph faster
10%.
@@babymetalenjoyer mine does exactly 5%
Normally, yes, till like 10/11 km/h faster than reality at high speeda
37 less then the actual speed, that was pretty good math
Pole: get ready to die
Screenshot 289 km/h !!

Its because the speedometer doesnt show the real speed. Top speed is anyway 246 of this car. Do a GPS test.
Measure when he is coming towards you, not away from you
bro if he opens his window his ear drums finna pop
No, every german could confirm the Opposite
@@ichschertzkeks9861 my bad bro
Angle.?
The cosine effect would create a significant error. Actual speed would have been faster.
Bro could no clipped to heaven at this point
To everyone a speedometer in a car has 7% deviation
Intense KEROSENE moment
In Germany the tachometers in cars show always a 110 % of the speed you actually drive
So if your tachometer says 110 you actually drive 100
If his car says 260 you have to subtract at least 26 kmh
In German driving schools you learn formulas for your breaking distances and to keep people out of trouble there are hidden securnesses
I can drive with 58 kmh trough a speed camera at a given limit of 50
5 kmh because my tachometer is 10 % off and 3 kmh because the law gives you +- 3 kmh for the inaccuracies of the speed camera
Don’t test it
Thats not specific to german cars. All tachos are like this. Imagine the legal trouble car companies would have if this wasnt the case
It's every country not just Germany
@@TheIceMurder2 Timo already enlightened me but thanks
@@Levelup445 Not all are like that i measured my friends Peugeot with and it was 2-3kmh off

The speedometer overstates a certain percentage
speedometer always shows more than you are actually driving.
up to 10% deviation are not uncommon.
A police officer actually said something like this, that the speed they book you a ticket for isn’t actually your actual speed they book you for about 10-20% less of the speed you were actually going at, that’s why if they stop you for speeding you were definitely speeding.
Remember that the car's speedometer is also programmed to be higher than the actual speed. Generally it is estimated to be up to 8%.
Toller Golf
Too much error
Bro went overspeeding
that device must take a picture when scanning
Car speedometers are required to show 10% more then what your actual speed is
You mean less, like speed traps?
Um where. All my speedmeters on my cars are correct and match my gps unless your talking about going fast like in the 150mph + range but that could be multiple different things as to why its off, Worn tires, wrong size tires, your differential, etc.
The speedometer usually displays about 6% less then actual speed.
Vw up to 10%
the swoosh sound ❤ …. DAMN I LOVE LIVING IN GERMANY 🇩🇪
And here I am in Australia being told that going 101kmh will instantly kill an entire family...
Lack of lane discipline and consideration of the drivers around you is what's killing families!
Ofc bad driving is the fault …
but the speed in the dashboard is higher than the actual speed and its a vw
In that speed I will play kerosene
Bro is tryna to create the new worst car crash in the world💀
The spedometer shows 10% faster than the actual speed
