    Some people have asked about non-asphalt physics, we can probably split the answer into two topics:

    Deformable terrain geometry: our sim already offers some dynamic terrain behaviour when in contact with loose surface materials. This is not done by permanently altering the terrain geometry, but with special treatment on the tire model and physics engine itself. Permanently deformable terrain geometry is outside the scope of our short-term tire research plans.

    Loose surface tire model: while our collected data is focused on asphalt-like surfaces, some of the insights we gain should be applicable to non-asphalt surfaces. We hope and expect that driving will improve beyond asphalt. For example, if we gained any insights on structural stiffness, then this would be directly applicable to all driving disciplines, including racing, drifting, mudding, rallying, rock crawling, even parking next to a low sidewalk.

    Will there be a tool for people to make their own tires or is it too early to say?

    Yeah it's too early to tell at this stage. If we end up creating any new tool, and it has no use for modders, we won't release it (it would mean unnecessary slowing development due to extra development/maintenance/support time and costs for zero benefit). While if such hypothetical tool could benefit modders, and there were no blocking issues (like licensing restrictions or alike), then chances are we'll consider releasing them for the benefit of the community, as we've traditionally done.

    They mentioned and showed that they have their own tire testing machine in the game, so hopefully, like the roof crusher, it will be available as a prop for modders to test their tires with.

    By the way you should do parallel research on the braking system, in particular brake disks, their heating, wear and tear and the effect of disk heating on wheel heating, which is actually very influential in circuit racing

    We cannot do a lot of parallel research, since we are not a huge team with spare people to work on these topics.

    That said, this is an area of interest for me. So in my own spare time, these past few years I've been keeping track of some simple brake-related information in my trackdays, under as wide a range of conditions/cars/compounds/etc as I could. Very simplistic data collection, and nothing like proper scientific testing in a controlled environment, but better than nothing. Note that this doesn't mean we'll have available dev time for this particular topic any time soon - that depends on whatever the relevant dev has on his pile of priorities above 'brakes'.

    Plus the fact that carbon-ceramic discs are lighter than normal iron ones. I remember the dev team ran into some serious issues with bugs in their first attempt at this topic with the Scintilla. And while I'm glad carbon-ceramic discs spread amongst the modern BeamNG performance vehicles (the Scintilla and both the modern ETKs, plus, along with the Selecta SportPlus 2R tires, I'd also love these brakes to be part of the Vivace S 410Q Arsenic, they certainly could remove some weight from the front end, carrying the 5-cylinder, and they would also remove the worry of fading, since the front brakes of the S 410Q Arsenic will fade from continuous deceleration sooner or later), some work on their weight reduction has to be done sometime in the future.
    Can't rush work though! :)

    pov minecraft updates, i don't think it will take that long, i think atleast 5 month
    --- Post updated ---

    we're talking about the new tire physics here, not updates in general

    the new tire physics will take forever to make, that video was just a little sneak peek

    Being honest, I'm looking forward to seeing potentially vehicles losing the bead of their tire due to significant side loading or pressure. Or some dork over pressurizes the tire and it blows the heck out over a bump. Im looking forward to future updates on here regarding every little improvement. I wanna see this and get an idea of exactly how slow these sorts of things take to develop
    --- Post updated ---
    I hope to see tire chains eventually. That would be interesting and I think they should test for that too. I want to hear and see tire chains being tested on tires and how the wear affects that as well. If they're really going all the way with that I've got to see this.
