It is so nice being able to turn your tank while you are driving up hill, with the old steering the way you lost speed while turning and going up hill at the same time, made it near impossible to turn on a hill.
I hope it is not intentionally, since you are suddenly locked to only being able to turn with your tank at max throttle until you hit the maximum speed at your current gear.
Honestly, the more i play around with double differential steering the more clunky it feels. What i mean with this is not the new driving mechanic that is clunky, that is awesome and feels a lot more smooth and fluid. It is instead more the controls that feel clunky.
Examples of why i feel that it feels clunky to control:
When you turn while going forwards, your tank is forced to go full throttle, and then tops the speed in your current gear. You can release the forward button, and it still makes you go forward full speed as long as you keep turning. As long as you have any forward speed, you will begin to accelerate when trying to turn.
Reversing does not function with the new steering scheme in the same way. You need to hold reverse constantly to reverse at the same time, otherwise the tank stops and turns on the spot.
The automatic gearbox suddenly is non functional while turning. What i mean is that if you start turning in 2nd gear, and it tops at 7km/h, then you need to stop turning to be able to turn at a faster speed, at the same time. Currently it feels a lot more like manual transmission mode when turning that the automatic transmission mode. So while turning it is the gear you are in that is regulating the speed, instead of the speed of the tank that is regulating the gearbox.
Suggesting for improvement:
If i had to change how the double differential currently works, I would say that you need to hold the button for forward to accelerate while turning, and it should not continuously accelerate when you only are holding the button to turn. This is to make it possible to regulate the speed while turning.
At the same time it should also be able to go up and down in gears automatically like it does when you just go forward. So if the tank changed gear from 4th to 5th at 18km/h when going forward, it would do the same when turning, and likewise if it changed from 5th to 4th at 14km/h because you are not accelerating, it would also go down in gear.
While this will increase the turning radius when turning, with it going from one gear up, this will be able to be regulated by you releasing the button for forward.
