Outdated as it might be, it is still interesting to watch. I wanted to just click it through as I do with porn but I actually ended up watching the whole damn thing.
As for you guys starting the never-ending development discussion again, I say that Scawen is not just developing tyre physics. He is developing a platform, because on those tyre physics (which will be more versatile than now), he can build new suspension types, maybe flexible body physics, weather conditions etc. Now, you'd have to program a new type of simulation for wet track. With the new tyre physics, he'd just set amount_of_water_on_track_polygon = 1.2l and off you go aquaplanning. But don't quote me on that
You need the best possible platform to build success on it.
