FGear Vehicle Physics (v1.4)

Hello, I have another complication, that was already discussed here. How to properly stop the car? There seems is no way how to hold hand brake from the blueprints (not by pressing the keys) when the fgear standard input is enabled. Or it is possible? Because only that is probably the only way, how to really stop the car (+ used Sticky Tire Max Speed).

If I will not use the hand brake, but only increase Rolling Resistance Coeficient to absurd number then the wheels are stopped but the car is still slowly sliding away. Even on a very small slope. If I will use also Sticky Tire Max Speed option then it will slide slower but still not stop completely.

So question is: is possible to somewhat simulate pressing handbrake from the blueprints when the fgear standard input is enabled? Or will be?
