I am from plasticine large-scale copies of cars. These are not just cars, they are very well detailed. Everything has been worked out to the smallest detail, and all this with our own hands. It takes me 70 to 200 hours of work to create such machines. It turns out really very similar cars. I shoot reviews and show what I have done.
And I also break them, destroy them in different ways. I know it sounds crazy. But this is all made of plasticine, and you can crush it. It can deform to simulate metal. I run into plasticine cars on various subjects and get pretty realistic accidents. It looks spectacular. You can even take such a car and wrinkle it right in your hands. You can't do that with a real scale model. If you like such creativity, then subscribe, I will be glad to you.
beamng drive also simulates the panel materials. such as steel, plastic, etc... your clay model car is weaker in comparison to those materials. that is also why in beamng the wheels didnt break like the model.
I would say, if you were to do this again, try to match the reverse speed of the Plasticine car with the speed of the one in BeamNG, I bet the damage would be similar then. If we were to take the plasticine version and apply that same reverse speed scaled up to the IRL counterpart or the BeamNG counterpart the reverse speed would have been like 80mph to 100mph in reverse which I don't think there are cars that can do that without any modifications.
