This mechanic was at last added to the game with the introduction of Elde 98, a Swedish SPAA. So when can we finally expect to see this mechanic for the majority of tanks in our game?
Go check out zenturions video on it. Download the mod to see it for yourself. Personally I loved it and I am spoiled to the extent that I do not wish to drive anything past ww2 without it (yea I know there are ww2 tanks with this mechanism)
I would suggest some tuning for it though: like pressing left or right turn while holding throttle should engage the regen steering and if anyone wishes to clutch brake and turn instantaneously they can press left/right without pressing the throttle.
