Better algorithm for speed sensitive steering?

[stan.distortion]

Kind of off topic for this thread but didn't want to start a new one for it. Tried changing the button press rates at carcontrolmap_local.h@281 to give a quicker fall when a button is released:

This did not want to post no matter what I tried:
carcontrolmap_local.h@293
- float sign = 1.0;
+ float sign = 0.3;

carcontrolmap_local.h@295
- sign = -1.0;
+ sign = -1.2;

I finally got the F1-02 car around a circuit The rates may be messed up for other cars though, that car seems to steer quicker than most others, and the throttle/brake rate could do with being different to the steering as its a bit on the slow side.
