I’m really impressed by a greate flash port of open source physic engine JigLib which is simply named JiglibFlash . You can see at the bottom a “5 minutes example” based on sample source delivered with port. I’m sorry for poor graphic made as simply as can be in Papervision3D. I’ve found this car model here and edited it in Blender to cut apart original wheels, because the car physic model require to set it seperately. As you can see I have no time to texture it. Car physic model have many configuration properties.  In this example physic is pretty not realistic but I think it is funny and playable. There comes to my mind a specific car races. I mean drift of course. Enjoy.
