Instructions are in the scene.
I had a concept of a self feeding engine I made and decided to implement it into this (because this other guy who's name I can't remember started making the circular ones too) and I did it because even though the engine has almost infinite torque, it spins the car around because of friction or something like that. So like this, the engines counterbalance eachother, to cancel out the spinning motion, and to get MORE POWEEERRRR!!!! Thats about it? I guess its fast (enough) lol
