Assets are not mine. Does not use constraints, the scripting goes as far as the forces which are calculated and applied, while roblox's physics engine takes care of the rest. This far from finished as you can probably tell.
todo: precise tire collisions, wheel angular acceleration by friction (im faking it right now), engine + transmission sim, mass-on-spring suspension model, sound effects, tire skid + smoke, better replication, ui, accurate steering wheel spinning
