Offroad car with homemade 4-speed auto

I posted my 4-speed automatic gearbox earlier and this is some car i made that uses the same gearbox. I made a small change to the original design of the gearbox by adding one more spring that will prevent the transmission from switching too early to 4th gear. I think its a pretty cool design so i left everything visible. Controls: WASD keys left control = brakes
