Is it possible to improve vehicles reverse speed?

[xxx73]

Hi guys

One thing that annoy me is the reverse speed of vehicles. I can drive pretty fast forward, but the moment I hit something or need to go reverse, it is barely moving.
So I hope it is a way to improve this in xml files. Anyone know if this can be done?

After more testing I find the setting that control reverse start speed, its the same setting that control start acceleration, unstickForce.

If unstickForce is increased, acceleration both forward and revers is increased also.
