Okay, comments you get.
I don't really like it.
Well, visual seems okay, as said before, nice use of sunset.
But the driving doesn't feel like a simulation at all. I could just start driving in 5th gear. You'll need some more scripting on this, something like this:
if (gear == 5 && CarSpeed < 20) Acceleration = 0,2;
if (gear == 5 && CarSpeed >= 20) Acceleration = 1;
The controls are a bit unfortunate too, how about this:
WASD for driving, space for brake, Q and E or scrolling for changing gear.
Shouldn't the lights go on and off automatically too?
And the sound goes crazy when you reach the top speed of a gear.
