Crash Testing Video: 2024 Ford Mustang Coupe NHTSA MDB Side Crash Test

Clearly you need to go see an eye specialist.

Have a look at the position of the pull force sensor:

I have not checked such videos of other cars though, but that was not my point.
The seatbelts in this video do not behave the way I would expect them to behave, that's all I wanted to say.

Of course the pretensioner is going to take up the slack and pull that sensor position forward, plus the inertia reel lock will allow some movement before locking. Clearly testing both in the US and in Europe will quickly find out if this is faulty, so it is almost certainly working as designed.

The irony of complaining about 'EV tanks' when the trucks on US roads are twice the size! Model Y v F150 - F150 is heavier and much bigger.

so… the context was cars. Sedans. Then the cybertruck was thrown in as an extra. It’s pretty well established that EVs are quite a bit heavier than their ICE counterparts, cars to cars, trucks to trucks. Vehicles of the same size will have different weights depending on how it’s powered and how the energy is stored. EVs of comparable size to ICE vehicles are heavier.

it’s not only about vehicle dimensions.
Hope that’s helpful in sorting out real-world from pseudo-irony.

interesting. if the airbag failed, the occupants would have smashed their faces into the steering wheel and dash respectively. The entire point of the shoulder strap is to prevent that from happening.

I'm sure the testing was thorough enough both here and in the US to work all that out and establish if the systems are working correctly or not. The shoulder strap never prevented the head reaching the steering wheel, hence why they were padded and then airbags fitted. In my first post on this thread I did point out the difference in airbags volume where seatbelts are fitted and mandatory, compared to those where they are not. The latter are much bigger.

There is much more to it when it comes to seatbelt design, pretensioners, load limiting, anti-submarine seats than you can see from an external view like that. I don't know the details of the Ford system but the most modern setups have load limiting features which allow the seatbelt to pay out and limit sternal / clavicle damage in combination with the airbag. I do know my S550 has a load limiting loop fitted.

Thinking about it a bit longer I agree there is good reason for the (slow) release of the seatbelts. By that, they reduce the acceleration/impact the body gets, similar to the crash structure of the car itself that hinders the body from being stopped 50 to zero in an instant.

Just looked weird at first glance how far the seatbelt let the dummy fall into the airbag.

Still I stand by my recommendation for you to have your eye checked in case you actually did not catch how much the sensor did move initially! missing *winking face with tongue*-emoji
