Scratch

I forgot to say when u let go of the arrow keys it must stop...

Since your car is turning and moving, I think that instead of giving you entire scripts, I might be able to help by fixing what you already have. So could you show your scripts or upload your project? Remember, if you don't want to do this, just say. 

Anyway, hello DaPoliteSniper and welcome to Scratch! I wish you an easy path to learning how to program!

Were you using the

when [right arrow v] key pressed

hat blocks?
Those blocks only work one at a time, and cannot be active simultaneously.  Because of this, your scripts would make the car turn left once, stop using that script, and start using only the move forward scripts.

Instead of those blocks, try using

when gf clicked
forever
if <key [right arrow v] pressed?>
turn cw (10) degrees
end
end

This kind of scripting can work with other scripts at the same time.

I think that you meant [turn (10) degrees] and not [move 10 steps], though other than that, you've got everything correct.

Blar, the move 10 steps was supposed to signify general script goodness, but I agree that could cause some misinterpretation.  Good call.

If I understand you correctly, the block you are looking for is the wait until block. Does this sample script achieve your goal?

when gf clicked
forever
wait until <key [right arrow v] pressed?> 
turn cw (5) degrees
wait until <not <key [right arrow v] pressed?> >
end

This script will control the turning, and the wait until blocks will ensure that it never turns more than 5 degrees from a single press of the right arrow.

This second script will control the movement

when gf clicked
forever
move (10) steps
end

EDIT: It seems time atrophies my skill with scratch blocks. I fixed the trouble I was having.
