They should put them in NBR24

@@fqeagles21 The Nürburgring probably can't afford to put them on the Nordschleife.

*fewer drivers (probably less drivers too considering that worse drivers may crash more often)

Thanks Marvin, that's very kind of you! The videos I create are exactly that, straight to the point without the extra fluff because that's the reason why someone wanted to watch the video. Have a great week!

Especially after what happened with WTF1...

@@KayoMichiels what do you mean? what happened to them

Yeah same i only some complex stuff from others but this is channel what i need to learn complex stuff about F1

Thanks Kilian 🤙🏻

Great idea!

Concrete walls are mostly on straights, so any contact would mostly be a side impact - whereas places where you're needing to slow the car down to absorb that fast energy is mostly in the corners!

@@mattamys Thanks for that great answer mate! Keep it up!

They are expensive, so only new tracks have them. Old tracks still use tyres, or a combination

For shallow impact angles TecPro barriers can actually be more dangerous than concrete walls. There is a chance that the car can get entangled in the TecPro barriers, which will cause it to be stopped within a very short distance, resulting in sharp deceleration. These deceleration forces can cause injuries to the driver. Instead when a car hits a naked concrete wall at a shallow angle, there will only be a minor side impact (which the safety features on the car should be capable to take care of) but the car can keep all of it's forward momentum. It can keep scraping along the wall for several hundred meters and dissipate it's energy over a long amount of time. Therefore the deceleration forces acting on the driver are way lower. So it is a matter of circuit design and risk assessment to determine which parts of the track are likely to see only shallow impacts (for example walls alongside a straight) where you would put smooth hard barriers like armco or concrete, and which parts might see blunt impacts, where you need TecPro or tire bundles. There is of course yet another type of impact protection available: the SAFER Barrier (which is an acronym that stands for "Steel And Foam Energy Reduction Barrier"). This type of barrier was specifically developed for oval racing, but has since found it's way onto many other circuits as well, including the Jeddah F1 circuit. On oval tracks the cars are always running parallel to the outside wall in close proximity, so pretty much all impacts into the outside wall happen at a shallow angle. That's why ovals used to have "unprotected" concrete along the outside, as this used to be the safest option. But in the last 20 years all oval tracks have been upgraded with SAFER barriers. These are essentially smooth steel guardrails mounted on styrofoam shock absorbers. The styrofoam will cushion the side impact, while the smooth steel surface allows the car to keep moving forward unobsructed. You can expect to see SAFER barriers on more and more F1 tracks in the future, as for shallow impacts they provide the best safety for the driver. For blunt impacts TecPro is the best option.

A quick coupling at the end of those tensioners for example

They are usually either printed onto self-adhesive film and placed on directly, or onto thin Multiwall Polycarbonate Sheet (basically cardboard but waterproof) and if a driver is going full speed into the barrier, this wouldn't be their main concern!

@@mattamys Ah ok, thanks for the explanation. I was a bit concern if those advertisement board could be a sharp object when it's being crashed into, seems like it isn't likely

Hahaha

I think the cars must shrink in size and length, then the Monaco GP will be exciting! Or you can change the layout
