This is the attempt 2 because i've made
another one (link) long ago (my first car!).
This hasn't got fuel nor temperature, but a very realistic spring lenght engine that needs a speed limiter, and has VERY realistic revving. See how smooth it is in the scene

.
I was too lazy to make polygon shaders, don't blame me
Controls: lots of them
Up-Down to accelerate-brake
A-Z to shift up/down gear
P, I and S stand for Park brake-Ignition-Starter. Park mode is already activated, so LOOK AT THE KEY.
END for clutch
The engine may stall under 50 rpm, but it's almost impossible to get so slow.
When you're on the rect, go the fastest you can and DON'T brake even after. You should get to the mountain at 160 km/h and jump there
Rate and comment. Especially rate! and if you want, peek on this scene's thyme, it's uselessly complicated xD
