My keyboard configuration:
E - forward
D - backward
S - turn left
F - turn right
R - slow
shift+E - turbo
S and F commands work ok.
How E and D commands works:
a) vehicle stopped
E - forward, D - backward, R - slow
b) vehicle in normal move
E - fast, D - stop, R - slow
c) vehicle fast move
E - fast(???), D - stop, R - slow??? - shouldn't be "normal". Or shouldn't be "fast" for SHIFT+E
This is how its working since OFP, everybody uses to that, beacuse its normal. Same with slow, hit forw key vehicle will move normal, hit again forw, vehicle will move fast. What is working wrong in your opinion? pressing forw key is accelerate vehicle, if you dont want to accelerate dont press forwards keys. If from fast you want to slow down use slow command, beacuse forward command is used for accelerate, and you are already runing fast. so command is repeated.
It doesn't work in this way since OFP. Rather since some patch in A2.
Simply lets try to change speed with command from fast to normal (with one key press).
AFAIK pressing twice slow does not result with normal. But i have to check it.
