These "challenges" are getting annoying... They have other things to do. And by the way, this isn't even a challenge, you're asking Gabester to hit a tree with a car at high speed. In my opinion, the only real challenge that was done, was David Fortsc's challenge. After that, everyone started copying him for some reason.
Why you are numbering developer challenges ? it so funny. Just ask what you want without labeling it with "developer challenge"
The thing that was different about David's challenge was that he hat accurate information regarding the impact. He wanted to see that, when the simulation was fed the same data, if the results were the same. Most of these subsequent challenges haven't had any accurate information regarding an accident in the real world, and it just seems like people don't care about the accuracy of the physics, they just want to see more cars wrapped around trees. If that's what you want, then go wrap the G2R around a tree on ashes48's castlegreen. It isn't really that hard to do, and would actually have more entertainment value than the previous challenges because you can actually do it. TL/DR: David's challenge was a scientific inquiry into the accuracy of the physics, this one is someone wanting to be entertained by seeing a car wrapped around a tree. Go wrap a car around a tree in RoR.
