Hi, finally got round to trying this, took about 30 seconds to fix
Actually there was nothing wrong with your code, the cmaera, moving the car forward and backwards etc were perfect, the model was just loading backwards. I fixed that by rotating it and using "fix object pivot" after
nice and simple

This looks to be a good start to a game, obviously you have to make the car collide with the floor it just drives through it at the moment, but its a good start
Personally after doing that, I would make the car only steer when its moving forward or backwards, cars can't spin on the spot
The "physics" of acceleration are good, I like the code for the camera and speedometer too
"btw you can keep the model of the car and textures"
Um no offense but I'm 99% sure you didn't make that as I've seen it before (I know you didn't claim to make it
) - where'd you get it from?
Its cool, it looks like the car from Sega Rally. I also remember a similar model being in t3dgm.
Anyway I'm glad I could fix this for you, good luck with your project
